3 years holding... wow, you do it very well mate, if I'm not wrong you buy those bitcoins under $10k, I would say something like $1500 was the cost when you first buy and sell the 5% is a nice amount, for sure you already recover what you invest in and still holding the 95% of your profit. So, congrats you play it really smart.

Now the question is, for how long you will keep holding the other 95%? do you have a nice goal to chase?
