Your query is out of line. Marketcap isn't just related with whales, tether and so on...
Am just scared if Whales decide to convert Bitcoin to Fiat.
Just don't. Whales aren't a bunch of fools. They are just waiting for the perfect opportunity to buy and turn a corner.
Will Tether keep printing more Tether to circulation?.
Yes, they might. Nobody knows what their next move is.
But that's irrelevant to your previous query.
Afterall, if you think marketcap is a metric for tracking the total valuation of Bitcoin, then you're wrong.
