I think everyone choose the strategy which he loves.
My strategy is divided by two parts:
1. Buy and Hold coins with a great potential (like Bitcoin, Ethereum and some others projects).
2. Daily trading of liquid coins
And also I am trying to get paid for job with Bitcoins
I do that too but I add buying shitcoins at a very low price that has the potential to be pumped. Instead of gambling I found a better chance to at least multiple my money in much better way. I decided to invest in shitcoins that cost around 1 satoshi. It is from my gambling fund anyway, so I can afford to lose it. Best is that if this coins from 1 satoshi ever rise to 15 satoshi which often occurs in yobit. I will be sitting with 1500% profit. This is literally a gamble in trading and I won't suggest you do that too unless you have an extra money that you can afford to lose.
