First, analyze what is your goal? Is it your goal to just earn a profit? Or you wanted to secure your future? But, if I were you if you have already profit and you plan to cash out your money when it has, then just get your profit and retain what your initial investment is. But, make sure to save for your future as well.
Same as like you I wanted to secure my money to invest in BTC for a better future. I'm a typical person who twists money for the future. money can at any time run out but investment and business will always grow every day. if you want to get a profit for a moment then spend your money in the right place
