Don’t listen to anyone. Even me. Even if you asked.
I invest in altcoins mostly (Because I have significant amount of BTC/ETH/LTC).

I want to increase their number, that’s why I am adding money every time to Altcoins. There are many chances to earn and just a bit to lose. Just HODL.

Even if your coin goes down - BTC goes up - you are UP in Dollars. Which is not bad at all. Or you can get coin that up in Satoshi when BTC is low. That way helps you to increase part of BTC. Or sometimes you gain satoshi (gaining part of Bitcoin) and Bitcoin raises too.
