I was having a lot of tokens in my waves wallet along with a few waves as well. I also sold all my coins and is planning to invest in some other projects that are running right now.
I had Minexcoin as well. But I didn't manage to buy more coins back in the day where it was extremely popular. Luckily, I've prevented losing all my hard-earned money in it as now "MNX" a defunct cryptocurrency. Sadly, this happens with most old coins out there on the market. They usually tend to get de-listed from crypto exchanges after the loss of interest from developers and individuals alike. It's best to "put your money where your mouth is". By balancing your investment between old and new coins, you can minimize risks as much as possible. The old coins to hold for the long term are: Bitcoin, Ethereum, Litecoin, and Monero. The rest will simply get de-listed from major crypto exchanges over time.
I'm still "hodling" the aforementioned coins, as well as, Waves, Namecoin, and Dogecoin. They're not as popular as other coins on the market, but their blockchain networks are still alive and running after all these years. Waves has huge potential in transforming the crypto/Blockchain industry with its unparalleled speeds and unmatched trade settlement engine (with its decentralized exchange). With smart contract functionalities, Waves could become a viable ETH competitor in the future. It's an old coin that has stood the test of time. But with the hype surrounding "De-Fi" and stablecoins right now, Waves is often under the radar of many traders and investors alike. It's the perfect opportunity to buy coins at a cheap price while it lasts.
The less old coins you "hodl", the better it'll be for your financial future. It's time to move on to the next big thing in crypto, by switching to new coins whenever you see the opportunity to do so. Otherwise, you'll be left holding the bag. I have many old coins which are no longer being traded on crypto exchanges, making me a bagholder in return. They may be worthless right now, but at least, their blockchain networks are healthy. I'm still holding them with the hopes they'll see renewed interest in the future.
