Holding coins and tokens and not looking back until you start hearing how big crypto market is will leave you in a very bad mood, I'm sure this must have happened to some people here as well, this is my new sad story, I have some moozicore and nxps in holding and I just heard that they swapped to new coins leaving my tokens useless
I hope others will learn from this
I've also had a similar incident almost like this in the past on an XLM coin and i store my wallet on web wallet and then they updated their wallet and after few years i back again to crypto activity i couldn't recover the password from that wallet anymore. because their new update not able to recover old wallet. if i calculate , there are several thousand usd there. so completely didnt follow any update so possible to lose access some coin.
Yes I have had the same as well. There was no wallet upgrade or anything, but the service of the web wallet simply discontinued and I didn't take that email seriously. It didn't have an obvious header or the word warning. I thought it is some advertising for whatever and ignored the email. After a couple of months I wanted to access the wallet. Website not up, tried to reach out to them and never got an answer. The coin was quite worthless though, but it was a lesson anyway.
