1. ETH
2. BNB
3. XRP
because for now, I only believe to investing in ETH, BNB and XRP for long term or short term investments, therefore I will never invest in any top altcoin other than ETH, BNB and XRP.
These coins mentioned here are pretty solid coins. As it’s a golden rule that diversify your investments, hence if you have Bitcoins in your wallet, and want to diversify the investments, then these are the best coins to choose. Now regarding the questions asked by OP, then I won’t like to buy the LTC and Doge coins now. This is because the coins have been now losing popularity and marketcap isn’t also rising as it’s used to do before. So yes will strike of theses coins from my investment list.
