2 years in crypto and mining business and i second this opinion.. never throw fiat into buying cryptos. You will make rash decisions and you will lose your money. I have always said that the coins you get from mining are really hard earned and you end up taking care of them as your own kids. So always prefer mining or earning (in case of steem).
Second thing is that all of your investments must head towards a single target i.e to get your hands at bitcoins while they are still trading at under 10k -15k. Once they soar above this price range, you cannot get them either through mining or purchasing. Then it will be a game of big whales. So keep some bitcoins in your wallet and don't touch them..
Very good post. I am gonna resteem it..
