They are not lucky. They understand bitcoins value ahead of us. That is why they bought it and hold on it even when it was still almost no value. And they are now reaping the profits of it. It is not too late. Bitcoin can still grow more, and someday someone will say, they bought at 600 and now enjoying millions in profit.
I agree with you, they are not that lucky. But those people who can read the situation and take advantage of opportunities, even dare to risk investing in bitcoin at the time
It is good if you can invest your bitcoins on the legitimate company or site but the thing is if your lucky to see one, but you will need a courage to gamble it and I think if you really don't want to risk you money or bitcoin then don't do it and just trade your bitcoin and there are other methods in increasing your bitcoin!
To improve the bitcoin became more and very safe is by way of trading bitcoin. Because the price of the bitcoin would certainly give appropriate advantage of patience that we have and it will not give harm to us if not in a hurry.
Yup! having a patient in waiting is a good feature for you and can actually help you think on what certain things you need to to overcome when trading with bitcoin, just as the saying says patient is a virtue indeed.
