Bitcoin will probably never get to 5000 imo. We're not even close to 1% at all, and if that were to happen, people would dump the price down to oblivion. There will always be a guy who dumps his bitcoin and kills the price. Of course I could be completely wrong and end up with a few thousand dollars in a few years. Only time can tell.
Yes it will take a long time before we are going to hit a price that is somewhere in the thousands. We are now to far away from it and I cannot even predict or guess when this is going to happen but it will at least needs 5 years.
