The GME short selling debacle has brought forth the idea of float to zoomers, boomers, and normies alike. So what is the float of BTC and LTC? The way supply is introduced in crypto is decentralized; the miners get the supply for confirming the transactions on the network by guessing the hash of the block, they exchange the supply gained for guessing the hash to cover operation costs, and that exchanged supply either gets locked up or continues to exchange hands until it is locked up. Since the blockchain is pseudo-anonymous the position of every single coin can be tracked. With this information you can literally check if whales are buying or selling.
Pro tip: You can find whale wallets through a block explorer. All the BTC and LTC being produced since the bottom in 2019 have been being accumulated. You won't see some of these wallets move coins to sell for 4-8 years at which point the price would be 100s of folds greater.
So what is the float? Going off the UTXO information BTC has a float between 1-3 million coins which is incredibly low, and LTC has a float of about 20 million coins (soon to be much lower >:D).
For comparison here are some companies with their respective floats:
GME float: ~27.29 million
TSLA float: ~759.56 million
Walmart float: ~1.38 billion
Now these companies can issue more shares if they wanted, but you cannot issue more BTC or LTC because they are in the purest form a piece of code. The protocol defined the block rewards, and the block rewards get halved every 4 years. While total supply remains fixed, the rate of which the circulating supply is introduced is halved every 4 years, and the supply that is circulating that isn't being traded is constantly accumulated. Resulting in the float of the total supply being reduced over time; this is why scarcity in it's purest form happens resulting in price to go up as there are more blocks produced, as hash rate goes up, as difficulty adjusts. It's a programmed moon. Very few things like this exist. BTC is first to market, and LTC is second to market so they should be treated as complementary goods like eggs and bacon; milk and cereal; gasoline and cars.
