In this current dip, market is showing a correction and after that we maybe seeing another upwards market soon. Atlcoins are many and you should invest wisely by which it will bring some profit for you. In this time, BNB is looking good. Eth, ADA, DOT, Reef, Beam etc are looking good to me to invest in. You can do your own research on those coins.
Ada, reef, and dot are my top choices these coins will bring profit in your portfolio. Many altcoins are good to buy and by doing a research it will really help us what to choose. The best before buying dyor and never invest on what you cannot afford to lose.
