KuKoin like many said.
But, also personally, I really like Pionex.
Feel free to use my ref code, but check them out without it if you arent comfortable using it:
https://www.pionex.com/en-US/sign/ref/xjSFH4cuThey are built around the idea of using built-in bots.
I personally do not use them, and do all trading manually.
It is a little quirky when first used, but they are using Binance (the main Binance not us) for their volume, so it is dynamite volume/liquidity.
The engine is very fast, and there are tons of coins/combos.
The CEO will answer questions in Telegram if the support cant answer.
Deposit/wdraw has always been smooth.
Fees are 0.05% market/limit.
Personally, I recommend NOT using leveraged coins, but they have a lot of options for that as well.
Also, Bitrue.com has been good but slightly higher fees. Still really good volume.
So apparently, I found out that Binance.com no longer allows US customers anymore even abroad. A while back i used binance and traded btc for altcoins there. I heard binance no longer allowed US customers but because im abroad pretty much all the time, well I didn't think it was a big issue as I log into binance.com without any issue. I also never was verified there. I heard it first was with US IP addresses that they banned but apparently its for anyone that is a US citizen. So because of that, I know i can't use binance.com anymore as an American abroad.
Now my question is... what exchanges can I use as an American that is abroad all the time? I know i could use coinbase/bitstamp without an issue from what I read online. I assume Kraken as well? But those would be for the main coins like btc/eth etc. But if i want to trade for altcoins, what are my options? I previously used bittrex a while back while abroad... but then they no longer allowed any customers from a particular state in the US... so i had to withdraw. I was also verified on bittrex and because of that, i could not use bittrex anymore.
I heard people who use binance.com in the US... then moved on to binance.us... which is basically almost the same thing? Its only with other us traders right? But is there a ton of volume there? And do they have the exact coins that are traded in binance.com? The thing though is i wouldn't be able to use binance.US while outside the US right? I would sign up for an account while abroad... so would there be issue with this?
