Crypto is hated by Central Govts throughout the world for two reasons: a) Unlike FIAT currency, or aam curency like chillar, notes, etc, crypto can't be controlled. Fixed amount, and no matter what gormint does, the value can't be changed. b) Illegal activities are rampant due to blockchain not allowing you to figure out who did what transaction other than the two involved in the transaction. Terrorists can easily fuck you. Govt can manipulate currency(due to India's manipulation, we are able to remain an exporting country, or we would have died).
Plus, crypto is highly volatile. Susceptible to a 51% attack. Only those with electricity(high amounts) will become rich due to mining, etc. Don't invest in crypto, unless you are investing in doge coin. That shit is just going up, up, up right now.
