Some people invest some if not all of thier asset in bitcoin. They are lured by its growing up value its equivalent to fiat currency but is bitcoin really safe and secure.? What do you think.,
SHA-256 is very strong. It's not like the incremental step from MD5 to SHA1. It can last several decades unless there's some massive breakthrough attack.

I am not a professional programmer or software specialist to explain this all to you, but read some stuffs about SHA-256 or how secured is the blockchain, youll probably get it in no time specially when you are in the information technology field. SHA is pure mathematics and there is no known equation that can crack this wide open for now.
Nothing is really secure on this planet, not even the planet itself!
But what you think is safe, the "real money" is actually the biggest scam you can think about, and it can crash in every moment.
So, bitcoin, even not 100% safe, is for sure much more safe than any fiat currency.
The technology behind this is safe for now, but we will see some major improvements if someone will be able to beat this, I think they would at least need another 50 years to do that.
