There is no legal maximum for the amount of Bitcoins you can buy. If your country allows you to buy any Bitcoin, you can buy as many as you want. Obviously, you can't buy more than there is. Bitcoin mining fees will disappear when Bitcoin supply reaches 21 million.
Miners are likely to earn revenue only from transaction processing fees, rather than a combination of block rewards and transaction fees. In addition, the maximum amount of Bitcoin you can buy at once is 20 BTC. For more information, see the fees page. When Satoshi Nakamoto created Bitcoin, he installed a strict limit on the amount of Bitcoin that could exist.
There will never be more than 21 million bitcoins. This limit, known as the hard limit, is encoded in the Bitcoin source code and enforced by network nodes. While there are limits on how much you can buy at a Bitcoin ATM per day, you are allowed to buy as many Bitcoin as you want. Miners can charge high transaction fees to process high-value transactions or large batches of transactions, with more efficient Layer 2 blockchains like the Lightning Network working in conjunction with the Bitcoin blockchain to facilitate daily bitcoin spending.
After the maximum number of bitcoins is reached, even if that number is slightly less than 21 million, no new bitcoins will be issued. If the Bitcoin blockchain in 2140 processes a lot of transactions, then Bitcoin miners can still make profits from transaction processing fees alone. Although the change would increase miners' revenues in bitcoin terms, the loss of faith in the Bitcoin network would cause a catastrophic and irreversible price collapse, leading to a net loss of miner revenues in fiat terms. But regardless of how Bitcoin evolves, no new bitcoins will be released after the limit of 21 million coins is reached.
Bitcoin is likely to hit its upper supply limit to affect Bitcoin miners, but how they are affected depends in part on how Bitcoin evolves as a cryptocurrency. These varying levels of identification verification will depend on the operator of the crypto bitcoin ATM, as well as the amount of money you are trying to spend or recover. These critics believe that as the block subsidy, the number of new bitcoins minted in each block is reduced every four years, miners, who spend resources to produce new bitcoins, will seek to defend their revenue stream by raising the supply limit beyond 21 million bitcoins. Using a Bitcoin ATM for buying (or selling) Bitcoin is one of the fastest and most convenient ways to trade cryptocurrencies.
In addition, although most Bitcoin ATMs will only ask for your mobile phone number and create an SMS password for you to enter, if you want to buy larger amounts, you may need to present higher identification levels. Although a maximum of 21 million bitcoins can be minted, it is likely that the number of bitcoins circulating will remain substantially below that number. As private companies, Bitcoin ATM operators strive to provide the highest security and customer support for their customers.
