PnL of this Put trade was only around 40-50 #BTC because part of the trade was a hedge and we lost the premium on the calls we bought, breakdown:
1) Short 65 x 10K Puts Jun 2020
2) Long 100 x 8K Calls Apr 2020
Now assuming the average LTV on $5 Bn USD is 50% (conservative), it means that $10 Bn #BTC is being used as collateral, pre-halving
i) We moon and these guys take out more loans to pump the price further up
ii) Or we crash >20%, causing 80% LTV loans to get liquidated and cascading liquidations causeing $10 Bn of #BTC to be dumped on us.
