If I may suggest I think hold everything is the best way.
The 6 coins of your choice are coins that have good potential in the medium to long term.
Even so, these 6 coins tend to go up when the market is in a bull run, they will also go down if the bear market is like now,
2 coins that might be worth selling quickly are Polygon and avalanche the reason is because they are network projects.
The current network project is pretty much held by ethereum and the Binance Smart chain in my opinion,
they are very competitive, while the others are still in the process of perfecting the network.
