If we go through the Indian law, all the things relating to the high rate return are illegal such as lotteries, batting and winning and I think cryptocurrency would soon be added and find the place in future due to its high rate return. It is very strange that Dream11 developer available at https://fantasycricket.dream11.com/in/ survived in India which is also the application on batting. If we talk about cryptocurrency, I think it should be regulated by proper technology and framing the law other than declaring it as illegal, so that there should not be any kind of hacking and terrorist activities.
