Invest more of your money and you will be survive because once market recover you will earn more.
Easy to say, but can you predict when it will happen? Still it is very possible that it is not the end of bear market. Price of Bitcoin still have long way to $1. I'm not saying that BTC price will ever drop to $1, but if was possible $20000 why not go down to $1000?
Everything is possible in a volatile market like this, and because this unpredictable scenario none of the options the author's post offers is enough to guarantee our survival. We can't rely our survival in holding, investing, mining or trading Crypto-Currency, it's too risky, being impossible to have a stable life this way. Crypto-Currency is a very welcome source of income, but it shouldn't be the primary one.
Anyway, although it's possible for BTC to hit $1000, even the most pessimistic predictions say it's unlikely for now.
