Follow Max Wright for great Crypto analysis. I put $10K over the last 4 months in Bitcoin (BTC), Etherium (ETH) and 5 other alt coins that is now worth $29K. Max has been saying that it will hit $100K by end of May. He says April will be a great month with 5 Fridays but will dip on the last one.
Two crypto coins on fire that are completely private (not supported by external wallets yet) are Monero (XMR) and Pirate Chain (ARRR).
I started in late Jan with $ 3K Monero at $150, it's now $340. Pirate Chain is even harder to obtain as not supported by Coinbase. I had to open a Tradeogre account. It was $0.13 in January, now at $2.05. Unfortunatley I just got in with $1K on April 7 at $1.07, but still see this going 10X.
Other alt coins on the rise are Uniswap (UNI) and Decentraland (MANA)
