As most of you might know that here, in India bitcoin is not considered as a legal tender.
As the Union Budget 2018 in India was announced on February 1 this month. The finance minister of India, Arun Jaitley's statement in that about cryptocurrencies in general was-
“The government does not recognise cryptocurrency as legal tender or coin and will take all measures to eliminate the use of these cryptoassets in financing illegitimate activities or as part of the payments system."

Here I just need to know why does the government not support cryptocurrencies. Gold is also not a legal tender and that too can be used in financing illegal activities but still it has a lot more advantages than this. Same as bitcoin has tons and tons of advantages for all!
What do you think about it? Is the government right for not recognising cryptocurrency as a legal tender! Or they should reconsider it?
