Bitcoin and blockchain are awesome technology but it is being most used in gambling , betting , casino, all bad fields is this what making many countries step back making bitcoin and blockchain tech making legal or creating negative impressions for people using this technology
Blockchain has name border payment with help of cryptocurrencies which is very interest secondly all the gambling you main mention of are all legal. Anything that has advantage simply has disadvantage not because its to good or legal but because people tend to use it in an unlawful so I believed bitcoin and blockchain has really cause more good than harm.
