Of course they do. You just to shop at the right place. Let me share some suggestions, you can always DYOR and consider them. They have or will have definite-real implementation in 2018:
1) ADA
2) RPX

I believe Bitcoin has a future in long term. It proved itself in the past years and it is getting widely popular. It just has a transaction fee problem atm.
What about the altcoins? Who does use them for real? Will people use them in the future for real purpose?
I only have a hope for ethereum and litecoin, but not for the rest. I am not even sure for eth and ltc.
If bitcoin solves the reansaction fee and time problem, I doubt eth and ltc even have a future.
