If this year will be a tough year for cryptocurrencies, then maybe by next year, a reversion of trend may be possible in response to this year's almost all-year-long fluctuation now. From 2019 onwards, i believe bitcoin and the rest of cryptos will also respond well.
This year has been a tough year already for those who want to see it as a tough year as I only see it as a year that gave smart people more opportunity to buy lower. Future is very great for bitcoin and the blockchain and even though this year may have been bearish, I certainly believe that in the long run, this is a year that a lot of people will always wish they have been able to pick the prices we are now as I see mainstream adoption gradually kicking in, institutions wanting to get a large play and countries beginning to find ways they can benefit from it rather than attacking the space.
this year is still hard for Bitcoin, and of course we can not predict what other year will be, , but I also hope that the next year will be much better for those.
The year has still not ended but at least for the last 3 quarters, it is obvious to everyone that we have been in a downtrend, but that has not changed anything about the bright future that lay ahead of us and only those who are very smart enough will be able to know and see the future before it even comes, just like some already saw now back in 2009/2010. We are all hopeful that next year would be a lot better or we could possibly just end up seeing the market try to do some good move upward, but nothing at this point is guaranteed yet anyway.
