Currently, BTC is only used as a store of value, which leaves other alts. From what I see in other alts, ethereum is spent on ICOs where the trade is one coin to another type of coin. Other than that, nobody advertises accepting payments in other currencies NOR do people seem to want to spend their cryptocurrencies on anything other than something that yields a profit.
So, the question is really about adoption. How do we expect cryptocurrencies to be adopted as valid payment methods when everyone is really using them as investment stocks? Will we only see proper adoption once the current greed and "quick buck" mentality subsides?
If things continue the way they are, then cryptocurrency will always and forever be destined as store of value assets and not really a currency that can be used in the real world?
Pointing to bitcoin, you just have noticed it but in reality bitcoin was being used to it's "intended form". We just don't have a clear source of this but bitcoin will never be legally used if it's not used for currency purposes. We can't hide the fact that their is an increase of merchants accepting bitcoin worldwide.
Pointing to other altcoins, I might agree to you. ICO's intended purpose is to used their respective tokens in their services but that's not the supposed thing that happened as getting profits is a must. But why it turns out like that? Because the real platforms and services of those tokens can only be used upon their established date based on the roadmap. So meaning, the actual service is not yet out as exchange coins will come first for trading purposes.
For me, just don't mind it and trust the process on the way.
