For the first time, when I move to cryptocurrency world (March 2016) the btc price were around $400... it was risen up to $17000 few days ago... 17000/400 x 100 = it's 4520% growth in 21 months.
There's a popular statement such as, the thing what it is existing next to the risk is the success.
Should I believe it and do what I didn't do 21 months ago?
Yeah. The risk taker will benefit more than those who are really afraid to lose and therefore does not risk even a little. In life, there is what we call a gamble. Everything is actually gambling. You need to invest not just money but also effort and time and other resources in order to gain. That is the secret of the rich and the successful. They are risking and therefore they are earning. How can you earn if you do not want to risk anything at all? Be patient, strong and believe.
