Third coin good long term investment less risk than other altcoin because can happening like Luna crash drop and loss much if invested there, I believe with Ethereum although still drop to $2,000 have chance back above $3,000 in few months later when bitcoin have stable on top price. Still hold about 100 BNB coin right now and hope one day later can reach all time high again above $600 and I really miss with BNB can pump to higher price, still waiting with BNB have new launchpad trough holding can get new coins.
BTC, BNB and ETH are indeed worth having as an investment.
Maybe you missed ATH BNB at that time and didn't sell it, maybe that's also a good sign, if you are able to hold it until the 2024 BTC halving, maybe the BNB you have today will give you a big profit. I don't bet on few months but years.
Be passionate in holding, don't panic. I'm sure these 3 coins will make new ATH in a few years.
