If you are a beginner then I would like to say that there are many coins available in the crypto market which can be a top investment coin and right now the market conditions are not up to the mark for short-term traders but if you are long-term trader then it is the right time for investing your capital and I would recommend you to go for investing in Bitcoin first and then invest small amount of amount in Bitcoin cash and then invest in Ethereum. As all three coins are the major coins for an investment you can equally divide your capital into these three coins and then hold it for few months or at least till you get your expected returns.
