My biggest regret, honestly, was giving up on mining after the value dipped slightly. If I had just kept my bitcoin without spending it until the end of 2017, I probably could've been set for life.

IMPORTANT UPDATE: There is a division of a long established company that is about to launch which has many of the features that we loved in USI TECH - here is more information on this new opportunity - NOTE: I will be adding people in order - as i receive the information that I need - (see below) http://www​.cryptoprofitability.com NOTE: We have needed something for the masses - We have outstanding opportunities in Masternodes, Trading software, Long Term trading BUT not everyone has $600, $2000 or $6,000 to get started - this is affordable to everyone and has all the positives of USI (that we loved) with low cost entry of $40, daily returns, compounding, great rewards for sharing and it's going live in the next week but without all the problems. Can be totally passive or a great business comp plan too. It's perfect for those who want a simple, NO brainer program, low cost to get going, and right at the start to get the first mover advantage. It was brought to me by a few well respected friends and leaders in the industry. I've been taking a good look and like what I see so far, although we have more due diligence to do. It makes perfect sense to lock in a position with a minimum entry of $40 for 1 Pack paid with BTC if only to see it in action. Each $40 sale (BTC) is split - $20 as capital to be used to generate daily returns - $20 to be used for commissions and company operation costs (Which makes it sustainable) Pack returns - up to 0.66% daily for 365 days paid on the $20 capital (so 0.33% per day based on total pack cost = approx 10% a month) - $20 capital returned at day 366 How are returns generated? Earnings come from a well established licensed trading company. - 80%+ from off the book BTC trading with foreign exchanges, BTC ATMs, Online Gaming Companies - Mining, Crypto trading on major exchanges - Forex Trading Pay Plan It's a 3x12 matrix with compression. - 3 personal sales to earn 6 levels - 8 personal sales to earn 12 levels Personal sales - 10% Matrix Commissions (with compression) Level 1 - 1% Level 2 - 5% Level 3 - 1% Level 4 - 5% Level 5 - 1% Level 6 - 5% Level 7 - 1% Level 8 - 5% Level 9 - 1% Level 10 -5% Level 11 - 1% Level 12 - 5% WHAT TO DO NOW? http://www​.cryptoprofitability.com With matrixes timing is important. All I need from you is to let me know if you want in and the following details. Have a listen to this recording of a recent webinar on the opportunity with the majority owner who has created over 10 MLMs over 10 years and all companies still trading today. For $40...it's worth a go to generate a great income - and please remember going forward - to withdraw your seed money!! - We know there are many variables we do not control, regulators, authorities etc etc - so protect your self.... use this to grow . Let me know asap if you want in...I will be placing people manually in key positions. Kurt http://www.eyelinetrading.com/kurt1

Going into binary trading is not easy at all . Most of you keep losing to your trade brokers because you don't make use of any strategy in trading binary, Note binary has gone beyond trading without a strategy, i have been trading for over two years now and it has been a real success that is because i trade with a system that has been able to lift my trades accurately .i have helped alot of people raise up their investment with enough proofs to show you. My one to one master class strategy would save you years of fund wasting if only you are prepared to learn binary trade. Binary trading is all about having a reliable broker, using the right strategy that nullifies losses and above all knowing how to read the trend . if you need assistance on how to make withdrawal from your account easily and find out easy ways to withdraw and how to recover the money you have lost, email me at uniqueimpression80@gmail.com

So you get paid in Bitcoin just for keeping track for other people. Same as accounting and book keeping. If a person good at math could learn how to do Bitcoin minning, they would be set. After a while they'll learn how to make money like the others who actually own Bitcoins

I forgot my wallet password and I had so much bitcoin in the wallet i couldn't let go I tried the 12 word phrase I couldn't recover damn thing I was hyper and worried a month later I was in Russia for a summit where they discussed so much about crypto currencies and it future during the break I was discussing with one of the delegate that attended the same summit I told him about my ordeal in crypto I was scared of investing more money he smiled and he told me he knew of a firm in Russia that would help out he said they are one of the set of hackers in Europe he told me would help. I was doubting I felt it was impossible with all read on crpto. He didn't let me down and never disappointed me. Been scammed twice but summoned my courage when I reached the computer guy (hackerrobert001atgmaildotcom) who helped put things together. Until you meet the right help, things might be difficult for you but once you key into the right direction, help will always come your way.

I smell a scam.... Ive never had problems transferring money around the world and im concerned there is little to no protection, u can rave on about how it works, but the bottom line is if someone gets your so called "key" ur screwed. there is no organization that will warn you someone is messing with your account and im doubtful you would get your money back. When you compare it to the systems banks use to detect unauthorized transactions its crap. I would use it for only minor transactions but the thing is Paypal already have that covered, and reinventing this overly complicated wheel is not the solution

So miners do something sensible beside dumping a huge amount of low entropy energy into haphazard information and heat - they keep this monetary system running. I'm pretty concerned by the ever increasing size of the block chain - if it aims to be the (a) currency of the future it'll need to prevent millions of computers wasting huge amounts of CPU time (and pumping out tons of CO2 into the atmosphere) while carefully munching through insane heaps of guano, oops, I mean data, that has accumulated since the early 21st century, every time you buy a sandwich.
Lance V (1 month ago)
It is too costly to use bitcoin for small items today. But people are working on solutions that consolidate the transactions off the blockchain,.then broadcast them as a single lump of transaction. There are other cryptos that dont use much energy at all. They are not quite as secure as bitcoin. But could think of bitcoin as your savings account and some other coins as your wallet spending money. They are working to make some of these coins interchangeable. One project is called lightning network. Other wallet type coins could be litecoin, ripple, nano, dash, monero, and many more. There probably will be infrastructure built that will accept all these coins but then again bitcoin would be the best most secure savings account
