First time investor: Considering buying the dip in ADA, VET, ERGO, ALGORAND, ETH or BTC. Advice?

1) These would be long term investments, I would just buy and leave. Money is sitting earning nothing in a savings account right now

2) I am not pulling money from essentials, or my emergency fund

3) I understand this is at risk, I could lose every dime

4) I'm gonna send all the "investors" that PM me after this post goat porn.

​

All that said. My thought was to drop $1000 in each, but I'd welcome advice as to my mix and also would like perspective on the gas fee issue with ETH. If I invest in ETH, will it be impossible to convert back to USD at some point due to fees?
