I honestly hope the Indians will be smart about this.
This is going to be their modus operandi:
1. First they will arrest the exchange owner. Then they will extract all the trade logs, complete with the Bitcoin wallet ids and linked bank accounts.
2. They will calculate how much BTC was bought / sold by each of the users.
3. Since they now have the bank accounts of the users, the authorities will contact them and ask them to pay VAT (can be 12.5% or can be 20%) + penalty for their purchases and Short Term Caps Gains (30%) + Penalty for gains from sales.
4. If you don't pay the penalty, they will seize your assets.
Sounds like straightly coming from Nazi's playbook.
What a shame for a "democratic" regime.
Thank God for: a) I am not a citizen of that country, b) I am not a female citizen from that country.
