Buying bitcoin has its risk just as any other investment does, but it has been the top performing currency in the world several of the past years. Bitcoin definitely has its ups and downs though.
Just need to buy for the amount of money that it is not a pity to lose and do not store all the funds in one basket. Bitcoin is still the best currency, but everything can change at any time.
I agree with you. Buying bitcoins from all of our money is very risky and i think it is better if we just put just a small amount of our money in bitcoin so if something happen like the price of bitcoin goes very low then still we can cope it and we will not be that person who regrets a lot. Investment is all about discipline and having a great dedication but always remember that don't be greedy because greediness often lead to loss.
