Each person trading and investing in a cryptocurrency must decide for himself whether to trade or hold altcoins.
I have an investment portfolio in which there are altcoins and I periodically sell them and buy new ones.
You can combine trading and holding - I do not see any problem here. Pick the altcoins with low market capitalization to trade them, and hodl such cryptos like Bitcoin, Ethereum, Monero.
absolutely right and I myself like that prefer to hold good coins like bitcoin, ethereum and litecoin which I still hold, because this year surely these three coins will bring big profits to me
