If you want to, then should select hodl altcoin the best. That was already clearly has a future. Because here we are going to hodl it in a long time. so we expect the profit we earn is also great.
I know the guys that make a lot of money on day trading but for me, it does not work. The reason is that I have a job that eats most of my time. Therefore, I hold altcoins that I invested in to get the profit later.
