Ah well, it's good to be bad like the way it's better make profit rather than being greedy. You cannot expect always good move from the market also I agree there are possibilities for massive pump this year but it's pretty risk too and yes BTC is a long-term star without any doubt I would suggest to take as much as you can and buy when it go down again.
Risk taker? Go greed and hodl as long as possible.
Taking a safe move? Go hodl half of it and the rest of it be greedy to expect 100000 usd or even more in the near future.
You cannot sell it all at once as you will only regret it later when the price skyrocketing and you cannot buy much, a lot of people doing this and that was big mistake.
