Btc-Alpha is not a scam, Ive personally used it many times. We have to get out of this habit of calling exchanges scams just because support for them isnt lightning fast. They realistically only have probably 4 or 5 people working on tickets and i imagine they're working on them in the order they were submitted so it just might take a little longer to get to yours.
BTC-Alpha got hit with a massive DDoS attack yesterday. The exchange owner is available on telegram if you need any assistance. I am sure they are backlogged at the moment, but they got all of my issues resolved 100%, even though it took a couple days.
The exchange owner and operator can be reached on Telegram at: @vitaliibodnar and @eliasolo, respectively.
Patience is a virtue.
