Am not sure but I think is because of the sponsor coinDCX which is a major sponsor on the IND vs Sl championship, I think it's a big attraction and while have attention of fans and views to be curious about the logo on the trophy with the logo almost always attributed to bitcoin, and coinDCX being an exchange for crypto-currency. Who are big and has a base in India, I may be wrong and they might have another significance for the Logo on the trophy, but I think it's almost has to be about crypto-currency.
Yes CoinDCX is sponsoring the T20 International tournament between Sri Lanka and India and before that in the ODI series they were sponsoring the Sri Lankan team and they are an Indian cryptocurrency exchange and they shut down when there was a circulation by the RBI and when that case was squashed by the Supreme court most of the exchanges that shut their doors opened up and now it looks like CoinDCX are back with a bang.
This is one of the ways the lost sheep can be found without being desperate. I believe they in for business now since the door is open to show case their recent precent as a cryptocurrency exchange. Since the only quick way to notify the public about there existence in the market is by sponsoring games and sports to rapidly inform people and investors to join their platform without benefit of doubt. I think this exchange be is only found in India because if their operation and targeted audience.
