Hi friend, first of all I have to say welcome to SN..... But to answer your question, it is better to consult with some other older and more experienced people here to guide you and hear their opinion. But if your decision was to change your currency to another currency and not register and authenticate anywhere, I think fixedfloat is a good option, it is very simple and well designed and you can do it. And do it with a smaller amount of 5 or 10 dollars first, if you could do it without mistakes, then you can do the amount you want. .... I say again, be very careful and definitely wait for the opinion of the experienced people who are here and see what they suggest to you and don't just make a decision based on one person's words. Good luck. I hope you got the answers to the questions.
