Bitcoin remains the number one choice because Bitcoin is clearly the number one coin with a very high potential value. And top-ranking Altcoins are also another investment alternative to choose from. After Bitcoin, these altcoins include Ethereum, BCH, Litecoin, ADA, Monero, BNB and others. However, I do not recommend you to invest in new altcoins that don't have a good reputation, because it is very prone to losing your assets.
