The question is what the reason for me to not believe in crypto? I think no strong reason for it. Cryptocurrency is good, many people have proven the advantage of crypto in various sectors. Many people have been successful in trading, investing, bounty hunting, or other jobs in the crypto business. This simply shows us that cryptocurrency is proven and deserve to believe by all people in the world. So, why not to believe in it?
By the way, I think you need to edit the title a bit! Change the world "rely" to "believe". On the thread, you state "believe", not "rely".
