Avoid looking for moonshots. Most likely you will get burned. Most coins that go up quick drop even faster. Stick to reliable coins which have been around and has hit new ATH in 2020. Bitcoin should be most of the portfolio long term, Ethereum is the next bet. Beyond that you could risk a small amount on projects you like. Polkadot, Chainlink and I like Aave which has great adoption. Look at Defipulse.com. Maker and Aave are top 2 adopted coins. I have not invested in Maker but that could go up huge as its market cap is 1/5th the amount on the platform.
