Never tried this one , I always use our local exchange to buy bitcoin then transfer that bitcoin in exchange and convert it in USDT. the only problem Is transaction fee when transferring my bitcoin to exchange
Thanks for your help.
Binance is limited up to $5000 and it takes credit card or so.
Looks like the cheapest option is via a local exchange indeed, buy Bitcoin then convert it to USDT on Binance and start the saving - she just needs to do it when the market is calm so the fluctuations between Bitcoin and USDT won't be too high (let's say it would take 30-60 minutes from the time she holds the Bitcoin until she converts it to USDT).
yeah bro her best option will be to buy from local exchange, why you don't look up localbtc on her behalf, maybe this would be an easy way for her to but btc and then convert to usdt, the market is indeed on the high side so probably best to wait it out and see if there will be some correction so she can get in, between why would it take that long to convert to usdt! is it not just sell to usdt from your binance account.
