Bitcoin will continue to become profitable in the next decade because it has a lot of more rooms to grow. The excitements are temporary gone beause of its price downfall and prolonged bearishness in the market. The bullrun that happened in 2017 may not happen again in the following year because it has to accumulate first for a year or before the excitement return to the market again.
I think 10 years is just minor compared to what it can be in the next 10 years. I know it won't be from 3 cents to 20 thousand dollars type of increase I can see that however that is only bitcoin we are talking about and not the crypto world in general. If you look at the crypto world there has been a lot of new coins and new companies built upon the crypto idea that is making a lot of ways in the world right now.
This means if the first 10 years has helped us this much than it means the next 10 years will be even better. Think of the phones, when the first phone was invented it was not remotely similar to the iphones we have on our hand, it improved a lot since the first day. I think same could happen with bitcoin and crypto in general, we can definitely have that type of improvement in our life time.
