Coins are developing, despite the limitations, laws.For example - Marinecoín.Now happens fair distribution (with proof of promotion ) and it is still going on, until the common fund runs out.The project is reviving, and I’m sure that the coin will gain value in the future. Because the following technologies will be revealed ahead: dev-less,  self sustaining, machine to machine, artificial intelligence.The community is growing, and this is the main thing for the project. Because developers do not need other people’s money, they need other people’s abilities, like the etherium.

I do not believe it is a bubble. Crypto's use-cases are boundless and the more it is globally adopted the value it has. It has no where to go but up.
