1. Bitcoin
Yep, that's it. Bitcoin is all that matters. Investing in 99.9% of cryptocurrencies, especially in the long term, is worse than investing in penny stocks.
Yeah Bitcoin will be the main for me for long-term investment. I won't look at so many other coins because in my opinion it won't be like bitcoin to slowly rise in the long run.
Maybe we will try Ethereum 30% invested and that's the coin I will shake in 2020.
For coins at stake tend to be more disliked because it's too long for me.
