Even though there is no assurance that Bitcoin's value will rise in the future, some investors think it might represent a worthwhile long-term investment opportunity.
Treating Bitcoin as an investment is the same with other assets too, like non-crypto related, where risks are always there.
Before making any investment decisions, it is essential to conduct your own research, comprehend the risks involved, and speak with financial professionals.
Bitcoin is not different than other investments with risk exists together with chance to gain profit. Risk with Bitcoin is even higher than other investments because regulations on Bitcoin and Bitcoin mining are unknown in future.
It is biggest risk for Bitcoin because with Bitcoin, without Bitcoin miners, there will be no confirmation for Bitcoin transactions on its public ledger. In addition, with Bitcoin, you have to store it in your own wallets, not in online wallets and in many countries you will receive no support from governments, police to find scammers or hackers who steal your bitcoins.
Bitcoin is sure an asset and also a store of value to safe you from devalue of fiat due to inflation.
Bitcoin and fiat currencies have different supply models. They are both inflationary but with Bitcoin, you know its total supply (21M) but you don't know total supply of fiat currencies (but you know their supplies will only increase more and more with time).
Bitcoin solves devalue problem from inflation and a rest challenge is how to increase its demand. With more adoption in future, demand will increase and I believe price will be higher.
