I am still holding bitcoin, litecoin, ethereum, ripple, dash, z-cash, ethereum classic, monero and dogecoin.
Most of these coins I bought were in 2018, so on most coins my loss is around 70-80 %
. When there is a new major pump, I will only keep bitcoin and ethereum.
In the past, I participated in quite a lot of bounties, unfortunately almost all of this tokens are completely useless.
Unfortunately, old coins are often replaced by the "new kid on the block". This means that most old coins are not worth "hodling" for the long term as they depreciate in price over time. Only Bitcoin and Ethereum are the exception, since they're still one of the most popular coins in the mainstream world. It's best to "hodl" these coins alongside new ones with active development and innovation, in order to prevent many undesired losses in the future.
Right now, there are many old coins that are still alive. But they're often "under the radar" as people are mostly focused on profits rather than utility. There are many good coins like Namecoin and Primecoin, each with their unique features in the crypto/Blockchain space. AFAIK, there are no other coins like Primecoin with an innovative PoW consensus algorithm based on prime numbers. It helps our society with the discovery of prime numbers, putting PoW's "energy consumption" to good use. Sometimes I wish a new dev team or the community would take over the development of Primecoin, in order to further improve its consensus algorithm. Being one-of-a-kind coin, I consider it to be a hidden gem. Namecoin, on the other hand, is a good old coin with a decentralized domain name system. It was the first cryptocurrency to ever make use of a decentralized DNS. Ethereum may have taken the lead in decentralized domain names, but Namecoin is still an alternative worth considering.
No matter which old coins you choose to "hodl" for the long term, it's important to never put all your life savings on them. The risks with old coins are much higher than shiny, new ones on the market. You could end up "holding the bag" someday if your old coin of choice becomes abandoned in development. This in effect, leads to exchanges de-listing the coin, putting trading activity all the way down the drain. You can still use the Blockchain if there is at least 1 node and miner on the network, though. I'm still "hodling" Spreadcoin, despite not having any exchanges available. The Blockchain is still alive and running, which makes the cryptocurrency useful. Let's hope that abandoned coins like Spreadcoin experience revived interest from a new dev team sometime in the future. Just my opinion
