Op it is unpredictable to suggest a pure promising project. Besides people will suggest bags of different coins at an early stage and you will be confused cause all project have good whitepaper, roadmap and will pretend as they are best untill scam. During bull run, it is better to invest well known potential altcoins that already experienced bear runs and haven’t died yet, rather still standing strongly with valid price. That will be better option in my point of view
this opinion is true though, its always better to invest in some well known coins that have fallen far from its all time high, because in bullrun you can almost be sure that the price will always at minimum come near all time high if you could invest at its lowest point of price then you can easily get massive profits.
its without the risk of the coin you invested are delisted since market capitalization of such coins usually are massive and the liquidity are also massive.
such coins are like ethereum, bitcoin, polygon and some others that have gotten the worst aftermath with previous collapse of certain exchange.
