If you want to buy bitcoins you can do it on all kind of methods, I prefer the localbitcoin method for safety if you want to invest a good amount of bitcoins.
Its safe and also very nice to do it on that way.
yes there is no doubt about this that investment in bitcoin is too safe, and i think it is still good time to invest in bitcoin as the price of bitcoin is still very reasonable for buying bitcoins.
Yes bitcoin is safe but it is risky so if you want to buy bitcoins for investments then for sure you are going to use that in investments.
Because there are some people who are buying bitcoins just for gambling it, but of course it is their bitcoins so they can do anything what they want for it.
And I would suggest buy now while the price is still low.
those people who buy bitcoin just for the sake of gambling with it are also trying bitcoin as an investment, they are doing everything wrong though. but they use it as an investment nonetheless and think they can make profit with gambling that is why they try it.
