The way Bitcoin is going, $1000 to $20,000 and then to $6,500 and all the bans worldwide and Bitcoin used in many kinds of criminal activities.
I will come back to Bitcoin after 5 years. If Bitcoin is there, it will go the silver way. Just as Silver was $80/ounce in 1980, Bitcoin can go back to $400.
If you come back to bitcoin in 5 years you most likely wont even be able to afford to buy 0.05 bitcoins. With the next halving in 2020 plus the gradual increase in price due to new adopters if youre leaving now you moght as well stay away because youll be kicking yourself.
