Well in my own investagations about the bitcoin price i see that buying bitcoin this time is more risk than buying bitcoin on last 2018, if we are going to buy bitcoin in the price of 50k to 53k$ we can really say that this is a risky type of buying because 53k$ is not a joke it is a big money comes with a big loss if ever btc will drop down after buying, i think the posible great option is to wait for the dip and then buy to avoid big loss, beause we really dont know after this bull run there is a big dip waiting and we need to be more careful on it.
Actually, every day that passes that Bitcoin does NOT die is another day it becomes less likely to ever fall to zero. So in terms of risk, I'd say every day you wake up and Bitcoin is still trading, your risk of losing it all becomes less.
More adoption, more recognition, more "too big to fail".
What may be lower every day would be the risk to return ratio. But even so, after 12 years, that return is far more attractive than almost any other asset I could easily access.
Which risk are we talking about here? =)
And also you can always argue retrospectively why it would be more risk today than it was three years ago as you have the information from today. Buying Bitcoin also depends on the time horizon you are having in mind. I would say if you buy and hold for two years you are likely to be alright, but if you need the money in half a year from now you could have a bad timing and have to sell in the middle of a crash, like many had to sell in 2018.
