I am not a bitcoin analyst just a novice. I dont know much about this subject but it is one that interests me. Thats why i decided to learn about cryptocurrency and join the steem community.
In my personal opinion (taking into account the recent growth rate) i think that bitcoin will grow to the minimum of $40,000 by april 2018 and then will start to stabalise just like real currencies. This means that hopefully the world will start to accept bitcoin for what it is, a currency. So if your looking to invest and wandering if its too late. I would say no its not too late yet as it is still on the rise and developing.
