Firstly this is not financial advise so do not take my word for it.  Investing in a top cryptocurrency by market capitalization will likely return less during the rally than an undervalued cryptocurrency. The challenge is in finding such projects that during the rally will provide enough use cases,  fundamentals, and marketing to create enough interest to create massive rallies.  I would advise you to take closer look at Chainlink(LINK),  Hydro(Hydro) and Blocknet(Block).  However,  you can always play it safe and invest in BTC,  ETH,  LTC, Monero or Dash. You'll still see at least 3x on any of those.
