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! Recently Insolar is swapping their token, I did not know about it, because I have been holding for two years but did not care enough as the price was very low! Today I was checking the Coinmarketap android app and saw Insolar coin increased by 530% but their ticker is XNS when I knew it was INS! So, I joined their telegram and get the updates about the swap! Unfortunately, If I fail to swap on time then all of the value of my holding coins will be zero! So, except Bitcoin, Ethereum, don't trust any coin for just buy and hold for a long time, rather keep updating yourself!
Of course, you made the right comments. However, over several years of participation in various ICO bounty campaigns, I have accumulated a lot of tokens. This was facilitated by the fall of the market since the beginning of 2018. For altcoins, the price has been too low for a long time and therefore it makes no sense to constantly check the possibilities for their exchange. Checking their telegram groups even periodically is very difficult. It takes a lot of time. I do this occasionally, as needed. I rely heavily on my friends and acquaintances who also deal with cryptocurrency. Yes, due to various swaps, sometimes you have to lose tokens already in your wallets. But nerves are protected. In many cases, such innovations in projects are associated with the desire of the team to get rid of part of the holders of their tokens. Therefore, they come up with various traps, so that we could not do everything in time. I lose some tokens, but during this time I get several new ones.
