Purchasing directly from your wallet in crypto seems like a faraway dream but now it is becoming reality as many projects aim to offer this service and much more.
The biggest issue is wallet security, and things have been moving in the right direction but we are not there yet.
Indeed, security is one of the main issues thay crypto deals with. Fraud and theft prevention should be top priority.
I think projects are starting to understand that and are allocating a lot of their funds to research and development of those segments.
Maybe this could be part of bounty campaign,to find bugs and vulnerabilities?
