I agree. Also I would add that what you say is why I argue against investing in a wide range of "currency" crypto coins. We do not need 10 coins that transact value as their primary use case, let alone 500 which is closer to the mark today. Just like we dont need 300 decentralized platform coins, but we have 'em anyways.
Point being, 90-95% of all coins will disappear one day, and likely the first to go will be those that clearly offer nothing but a promise of future development.
This is why I primarily invest in crypto that has a use case today, and preferrably a revenue stream to support their growth.
Some of my favourites are TenX, because I see them as a leader in making crypto spendable, and there is a market for that. More than 100,000 users in Europe so far have signed up and are spending millions of crypto already, generating fees which the company can sustain its growth upon.
There are others, like Steem, and the value it gains by the increasing appeal of Steemit.
Or Ethereum or Neo which already have many apps coming out for their platforms.
I guess what I am saying is if they aren't already being used by a customer base, altering how a traditional business model can operate, then they haven't proven themselves as a meaningful crypto, in my opinion.
