Crypto exchanges make their money from withdrawals and trading fee that's why some have high withdrawal fee and some are so damn affordable but what about crypto wallets? How are they making money?
I mean it's damn hard to build a crypto wallet that's secured but where is the money coming from?
It is not all the Crypto exchanges that charge transaction fees, some of them did their trading without charging any fees from the traders. Like the experience I had from Ramitano and finance. If I sent 0.002 or 0.005 from wallet to binance for exchange, I only pay a transaction fees from my wallet while the exchange platform (binance)didn't charge me anything. So I don't know where they are getting their profit and pay workers. For the wallet, they charged fees base the blocks(nods) at the moment. Example:

This is how wallet get their money from mining.
