For the first pick, it is sure enough if we choose Bitcoin over all altcoins., Bitcoin is the king of cryptocurrency and we have seen how worthy and promising the Bitcoin investment is. On the other hand, investing in altcoins may be riskier. But of there is Etheereujm, I think that it is less risk. I also love Ethereum because this is the best altcoin. That is why if we can divide our money into crypto investment, we can invest both in Bitcoin and Erhereum, why not?
