I prefer to work with cryptocoins which are familiar to me. That is why I make investments into cryptocurrencies which are in the top 20 on the market. Bitcoin and Ethereum are the main assets for putting money in. This is my opinion and I think it is true opinion!
I also prefer to invest in old altcoins that are included in the top 20 in the market, it's much safer than investing
in new coins, I prefer holding old coins that have good potential and prospects in the future
