better you can invest in bitcoin right now because if you are not investing in bitcoin and waiting too long to be able to invest in bitcoin it will make you lose and will make you run out of time and not be able to enjoy the time to get profit.
I also hopeful about the future of bitcoin, but the current situation tell that in this year it is not possible because of the rough market situation. Everything is red today and there is no green signal in these days. Therefore I think the price will increase but it will take long time. Now people are optimistic that the next year 2019 will be good for bitcoin.
Current conditions are indeed in a bad condition. There are so many steep cliffs in 2018 and this is very different when we see 2017 where Bitcoin experienced very good development. But don't stop hoping because in the end we are all sure that crypto will become an era in the future so that other Bitcoin and coins will be very likely to experience development next year, 2019 hopefully it will be a good year because it is the best opportunity to be able to continue to develop the market crypto to go to a much better era and increase in coin prices is something we look forward to.
