If you want in then just buy in, you decide what you do with your money. Also, don't be scared on hearsays saying that bitcoin can drop to altcoin prices this year because it can't. It is very unlikely for it to happen but if it does happen, it would be the greatest dump we will ever see on the history of cryptocurrencies and it will be remembered throughout the history. If that happens just believe in bitcoin and hodl, it will surely go to moon again after some time of staying in a low price.
