I have invested in many crypto assets. My top holdings are:
1. XRP (On Demand Liquidity)
Most usecases of all crypto, fase, scalable and backed by a big company to finance the development of the ecosystem

2. Bitcoin (btc)
Best known and adopted crypto brand with a big community.

3. Tezos (XTZ)
An award winning platform and more scaleable than Ethereum. Therefore more potential for a rise in the future.

4. USDT
Stablecoin for trading in the volatile cryptomarket.

5. Brave Attention Token (BAT)
Best internetbrowser with their own token. Their market and ecosystem are expanding every day.

There are of course more promising cryptoprojects, but remember, there a lot (and I mean a lot) of cryptoprojects with a minimal usecase which solves no real life/company problems. I suspect that 97% of the cryptoprojects will not survive so be "picky" and do your own research before investing!
Thank you for reading.
