I think It's a good time to invest. Bitcoin will experience a lot of price changes but has the potential to grow big in the coming years. I'm sure bitcoin will be much better than now and bitcoin has already begun to be accepted by some people, bitcoin much changed the lives of people who once lacked now enough people, knowing bitcoin. So we do not have to worry about bitcoin in the future, all definitely improves.
Although we can not predict bitcoin but we can be comfortable with the fact that bitcoin will not work anytime soon.
