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 coins in the market and new ones keep coming which we need to understand that we can always buy and hold to try to earn some profits from them. Selecting a particular good coin from random of bad or scam coin can be very difficulty and we need to be wise when making decisions about what coin to buy and what coin not to buy. We can always make money from buying good coins but the problems comes in when we don't know how to identify good coins in the market. If we still want to make money then we have to be prepared to join coins or community that would keep updating us on recent new tokens to buy.
