If what is being said is true, then that is good, and you have a business, and your parents helped you somehow. There are rarely parents who support their children who believe in Bitcoin.
They don't support you because they don't understand bitcoin yet, once they understand they will support it with both hands. My parents knew I made a lot of profit from bitcoin, and later they even encouraged my younger brother to follow me in investing in bitcoin. Most parents and elders do not support bitcoin because they do not understand what it is.
Then another thing: in every business that we build, regardless of it, we can use cryptocurrency other than Bitcoin as payment. Just so others can get used to always using it as a mode of payment, that's why when there is a problem with the Bitcoin network due to congestion, it is not advisable to use Bitcoin. It is better to use another cryptocurrency than Bitcoin, such as Bnb or USDT, and the network to use is either trc20 or bep20, depending on what you want.
OP said he removed other coins from his payment method after receiving some advice from people. I don't understand why people advise that when it's a viable solution, maybe they're bitcoin maximalists.
