1. When BTC price recovers to $60K and reaches $90-100K, top coins like ETH, BNB, ADA, XRP, EOS, IOTA, NEO, LTC, DASH, BCH... will grow very strongly. It is a safe choice for investors when up-trends are only confirmed.
2. My favorite altcoins are EOS & IOTA. In addition, XRP & VSYS are also very potential.
3. New gem: I like KONO and NEAR. I bought KONO for less than $0.3, and NEAR is waiting to buy at $1.8.
