Don't hold some good but random altcoins for a long time. If you still want to hold then don't leave their telegram group or other social accounts, check updates on a regular basis. Because if you just hold and keep it in a wallet for 2 years then who knows after 2 years your coin's value may turn into zero value, because of the swap!
I lost many coins because of swap things!
Sometimes I question the need for these swaps. There are projects which swap immediately they are launched and one begins to wonder why they didn't swap before launch. My fair conclusion on that is that such projects had a bunch of confused team members and a shaky end. However, I don't have issues with projects that automatically swap their tokens and effect the change in all tokens held in private wallets. It's a good way to go. And not the manually done swaps.
