The simple, easy, and best way to make more profit is to be calm and keep patience. Analyze the market carefully,follow it then you will know the time when to invest or sell them or buy them. Or simply sit for trade.
Very nicely put - Staying calm is a must in Crytpo world ! If you panic after your investment drops then you end up losing your money .
Only invest in top 5 cryptos like BTC, ETH etc and don't invest in ICO's unless you do a thorough research , You can participate in bounties and airdrops if you have some free time .
Good luck !
