Remember.....that person that managed to mine 30BTC when it was still possible to mine Bitcoin probably felt it was not worth it when he was looking at others with 10,000 BTC but that person is smiling today I guarantee it.
I am that typical person who mined more than 30 BTC equivalent of cryptocurrency (e.g. 5 BTC, 1000 LTC, 1.2M DOGE, 5M BCN, 1000 DASH etc.) during 2013-15. On that time, I definitely envied that people who had 10K BTC or 200K LTC.
Unfortunately, I am not smiling now since I lost them due to impatience in daytrading cryptos and futures (yes, there is 20X leverage trading on LTC in OKcoin). The good thing about STEEM POWER, they are safe from hubris of impatience. My goal is make 40K STEEM by 2018, yes I have to buy loads in fiats in next couple of months. Mining them (e.g. earning through blogging) is not easy as through 2016-17.
I hope STEEM sees similar returns like BTC ($600->$6K) and LTC ($3-$80) from 2013-15 in coming years.
