Irreversible transactions are a huge advantage ,if you compare crypto to the paypal scam.In PayPal,you have to rely on the mercy of their dispute resolution process and the mercy of your customers.
I agree. Paypal chargebacks are a menace and have affected me and many people so many times and Paypal does not care most of the time which is why I personally support the irreversible nature of BTC.
There is no guarantee that there won't be any more scams even if BTC TXs becomes reversible in nature.
