I will suggest for you invest 50% in Ethereum and Bitcoin and other 50% split in two or three coins which price is less than 05 cent and are in good exchanges from last two years and have at the bottom.
YES! I totally agree with your advice! Investing in BTC and ETH right now is a good way to ensure that there'll be profits. The reason is that BTC and ETH is increasing its value. Furthermore, people are believing that there'll be a bullish season for the market. Especially for ETH, ETH is going to launch ETH 2.0 which create too many hope for traders and investors. ETH and BTC is the way to go, mate!
