I don't know jack about blockchain or crypto to be honest. I just took a Udemy course and it sparked my interest while not really teaching much. However it seems from my minute understanding that there's a huge risk with ads. I use a site called Swagbucks and one of there video channels, N-Crave, is notorious for ads sneaking hackers in. I actually just saw in these very comments someone was hacked thru someone piggybacking!
How much more security would be needed and at what cost?
