Hey Rushil! I was associated with Fx Choice sometime back for around 8 months. I appreciated their trading conditions and platform and never had any issues with deposits via the wire transfers. They do offer tighter spreads and unlike many brokers they have exotic pairs to trade on. I just had some issues with my withdrawals and had trouble getting my money back. The huge fees associated with fund transfer also bothered me sometimes as there are brokers who offer competitive conditions at low fees and commission. And as far as VISA is concerned, I doubt they offer VISA option to US traders since I was never able to transfer through it. I see they have added cryptos in deposit/ withdrawals. Hope it makes things easy. And Yes even I like both MT4 and MT5 in one platform which is easily accessible and technically advanced. But I have not much knowledge about MT4 installation on wine or any application. I guess I was able to answer some of your questions. Good luck!
