The circulating supply inflates because of the block reward. At every halving, the block reward is cut in half and the inflation is likewise cut in half. 

There are on 21 million bitcoin that can exist, and around 90% have already been mined. As time passes, the inflation of bitcoin will approach and reach 0. Mining will be incentivized by transaction fees. 

Monero on the other hand will inflate forever due to its tail emissions. Bitcoin is naturally deflationary, meaning every coin increases in value, while Monero is naturally inflationary, every coin decreases in value. Monero’s rate of inflation is similar to gold, but that means it is not as good of a store of value as bitcoin. 

Blockchain transparency is a feature, not a bug. Bitcoin is superior in every way. 

How does buying Monero with a debit card offer any more security than transacting on a Bitcoin L2 that mimics Monero? Small changes to the LN could enable true onion routing that fully anonymizes transactions. Even if BTC L2 cannot perform as well as XMR in terms of privacy, the only logical solution is to exchange BTC for XMR when privacy is needed, considering BTC is harder and a better store of value.
