In my opinion, No one is really safe when you hold Bitcoin it is always prone to hackers and fraudulent things that are online, I am not judging their service because I don't have any experience in using it, but if it is online it is always prone in getting hacked, if you would think about exchange getting rob by hackers, All services online can become victims and I think there is no 100% perfect technology there will always this flaw that can be expose. I think there is cold storage that is 100% offline that is really safe for storing cryptocurrency.
Cold storage is a great option which some exchanges are using to protect their digital assets and those entrusted to them and I think so far they are the safest platforms and as for others they should start praying that hackers will not be interested with what they are holding otherwise it can be a hell of an experience and can even put the death certificate into one's business. This is one of the biggest challenge I see in the world of cryptocurrency. Now, if big banks can be subjected to successful hacking, much more with small platforms who can not afford the highest and the most effective security technology. No wonder there are some people who are staying away from cryptocurrency as they are aware of the risks including getting hacked. For individuals, the best way is to use hardware wallets just don't forget the keys.
If people need protection from volatility, there are futures contracts exactly for that. They are if you are confident about a certain deal, and you can win or lose depending on what really happens at that point in the future, but at least you know what to expect. Interest rates are boring anyway, IMO. We have some "incentives" to hold money in the banks in my country, but this percentage is miserable. If people need protection from hacks, then they need insurances for their bitcoins. Some insurance companies are now offering deals to insure cryptocurrencies, but this market niche is still fairly empty, although I think it won't be so for long.
I read somewhere that one big beneficiaries with hacking and ransomware are the insurance companies providing their services to different platforms who are looking for some protection and assurance that if something can happen they can still recoup even part of what they lost. Actually, this is going to be a booming business and the market can be big. Just another business is born because of this problem.
