Well I do think there is alot of coins that are showing profits in this 'bull run'. We do not know which coins will give us big profits.
But for me I like to invest in coins in the top 10 for the marketcap. Ethereum is always a good alt coin if we want to add to our crypto portfolios.
New coins are emerging day by day and it become difficult to select a profitable coin and everyone is in trouble and wish to not choose any scam project. During such situations only top coins can make you profitable and you can avoid scam project if you trust top coins more often than new one.
Among altcoins bitcoin is truly a trusted currency and one can choose altcoins without any doubt of success but there are also some other altcoins like BNB and Solana which shows greater success and selection will be more profitable for coming halving.
There are so many new coins in the market but I am only looking to invest in meme for only a short period of time so I can always make some quick profits and jump to the next one. If I found out that a particular project A has what it takes to be bought and hold for a long time, I will do that so I can always make quick profits from the crypto market to buy more token.
Thise that knows what to buy and when to buy would be making lots of money.
