As for me, I don't even see any end to cryptocurrency. I see cryptocurrency like the era of internet businesses which later evolved to many global companies. Cryptocurrency will be here forever but it will continue to evolve as time goes on.
End of cryptocurrency? That's not going to happen, we are improve and we are in the early stage now. There will be more improvement to come and it seems is getting ready to take off to the moon now. Just watch, I am expecting that this year it will change the way people sees bitcoin.
It's not a bubble, it's a legit move and we might surpass what we have previously achieve.
