Given that Bitcoin rises to around 15k this year,
I don't know if your grasp of English is just shitty or you're deluded, but it is absolutely not a given bitcoin is going to rise to that level. Nothing in life--and certainly not in cryptocurrency--is a given. Sadly a lot of folks tend to think the way OP does and depend on a never-ending increase in price. Bull markets do tend to make fools out of a lot of people, but we're not even in the midst of a raging one at present. Bitcoin currently is stalled out at $7500 and nobody knows where it's headed. My advice would be NOT to count on it or anything else doubling this year.
