BTC, ETH and BNB are still the best at the moment, even though recently the cryptocurrency market is experiencing a pump moment, because the halving has not yet occurred, buying BTC as an investment instrument still has the opportunity to gain profits for the next few months or for mid-term investments.
Meanwhile, ALT SEASON is not yet visible, this is usually a phenomenon that occurs during halving, usually after halving or after BTC SEASON. The safest is top coin for investment needs, for transactions I like LTC and DOGE because the transaction fees are quite low.
