I'll agree with anyone saying that this NFT craze is idiotic, and that most cryptocurrencies don't have any utility, but to say that crypto isn't fast, cheap or secure is like saying 90's internet couldn't have webpages with pictures because gopher couldn't have pictures. I send money to my sister from my algorand wallet to hers in one second (literally), any amount for something like $0.0001. I'm not well versed enough in security to make any claim about safety, but if I have to trust someone regarding the security of some software, it might as well be this company's founder. Right now it's by far the best method to send money accross the globe.

edit: forgot to add that it's also very energy efficient
