Amazing stuff. I got started with my first Asic Blade (13 gh/s) when BTC was around $70. The growth over the last 6-7 years has always been impressive to me, but 2017 took crypto to a whole new level. It will be interesting to see which of the big 2017 ICO's pan out and how many end up as a bust. Also, everyone should be protecting their accounts and coins from hackers using the best means possible. The recent sudden growth of crypto has unfortunately brought with it an uptick in hacking/scams as well.
With that said I hope everyone has a great 2018. To the moon....
Security is indeed a very important topic for all of us but that is also true for all technology now and even more in the future.
