Let me remind you understanding FTP.. You can get tide up with your local ISP and you might get serious bandwith traffics are capped up to 250GB to 300GB Per month.. ANYTHING GOES over, you have pay hefty monthly fees, also maybe harder to share more than 1 users and can tied up your internet!
Check your local ISP what is your capping bandwith monthly! I was ex-ftp user my own hosting.. Not cheap!
