Small transactions: Remitano and Yellow card are recommended.
Big transactions: Bybit zero fees is better.
If it comes to KYC, there are many of them that you can easily trade small amount of money. It is not easy to find on Bybit but it is also there. Bybit has been the worst to convert low amount but it is still there. On others that I know, you can easily find it while some allow you to go for express and some display it easily in a way you do not have to scroll down too much. I know that Bybit is the opposite of this but you can also find such ads after you scroll down very well. Other exchanges are not like Bybit as you can still easily trade small amount of money. There are some of them with zero fee also.
Their exchange, their Rules - just the same way they have a static BTC gas fees at $30+ . The minium deposit of BTC was increased to $40 recently.
$40 is too much. Most exchanges are having far lower minimum deposit. Some people do make mistake and have to contact customer support which can be frustrating. On exchanges like OKX, I know someone that their money were stolen by the exchange like this. I do not have people that is using Remitano.
If bitcoin increase more, it is likely they will increase it. Having equivalent of ₦70000 as the minimum deposit is too much is my opinion.
What do you mean as bitcoin static gas fee? I guess you are referring to the exchange.
