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?
There will always risks associated with anything we do in life and in fact sometimes not doing or deciding on anything at all can also be risky. People who are dreaming of something more in life and who wanted to achieve a dream have to face the risks involved though there are also ways to minimize those risks.
Those who risks something when Bitcoin was just starting and did not give up their share are now reaping the benefits they never thought will happen one day. they are the lucky ones but they took a gamble and it paid off well especially that Bitcoin is now very valuable. Yes, next to risks is success though there is no guarantee whatsoever here.
