Well, these are the only the coins held on Coinbase, which doesn't actually give us any indication of the 15 most popular coins in general. Additionally, I wouldn't say that the average hold time has anything to do with popularity. Can we really say that Ethereum Classic (ETC) is more popular than Ethereum (ETH) and Bitcoin (BTC) just because it has a longer hold time? That's ridiculous.
Personally, I think that hold time has little to no correlation with popularity. Certain coins are used more than others and have more utility, hence why the stablecoins have a shorter hold time. Doesn't mean they're not popular.
If you spend a lot of money, do you think that means you don't like money? Ridiculous.
no, but it shows that people more interested having certain coins in their wallet.
which means most of them choose a well known and an easy to find one to get more information as part their pre-investment on their own personal research and also for me could be considered how popular that coin.
it is not hard to understand.
however this is just a statistics based on their point of view, you can creates your own statistics if you feel disagree or something.
chill and let's discuss things in friendly way
, peace out.
