I can see the utility of bitcoin, and I've used it to buy things online. If a business can't accept credit cards or PayPal for whatever reason, they can always accept bitcoin. Now, what about the rest of the altcoins that have their own blockchains? IMO, they're mostly useless in practical terms. And these tokens that run on ETH? I have what I consider an outsider's opinion, because my understanding of how those tokens work is abysmal. What I see are a bunch of scammy projects trying to force "tokenization" on things where it doesn't seem appropriate to do so (in my novice opinion, again).
I think the ICO market is going to come crashing down eventually precisely because there's no real-world use for these things. Right now there's just a bunch of speculators trying to buy the next bitcoin--and it's not going to happen. Once everyone realizes these tokens are useless and worthless, it's game over, just like those worthless internet stocks in the 1990s based on businesses which never had a shot at making a profit. And I have the same feeling about the fate of most altcoins as well.
We'll see. As they say, the market can stay irrational longer than you can stay solvent. The only way I can see to stay solvent is not to invest in these tokens, and the market for them is extremely irrational to say the least.
