What are the 10 cryptos everyone should have at least some dust of?

TLDR : What are the main blockchains you think everyone should have at least a few of their coin for future transactions?

I have actually only used a few blockchains for now. One annoyance i encountered is when i needed to exchange a token i had acquired for some other crypto. To be able to sell it, I first needed to send it to an exchange. Which is done using a blockchain transaction. Which needed the blockchain's coin to pay for transaction fees, not the token! So i also needed to buy a small quantity of the chain's coin. Then whithdraw it from the exchange to the wallet that has the token. Which had a base fee that took most of the small amount i had bought!
For the few cents worth that were needed for the initial transaction, i ended up spending a few dozen dollars worth! I could even have 'unprofitably' mined that coin, and it would still have come out cheaper.

On another scenarii, there were occasions where i could not take advantage of an upportunity on a token because i had none of the base chain coin to transact fast enough.

So, what are the (10?) blockchains you think we should have at least the amount of the coin to run a few transactions?

BTC? ETH? MATIC? SOL? Binance chain? Something else?
