Will the transaction fee will high if I send small amount under $50
Oh, if you do the transaction fee now, it's still a bit expensive and will be deducted from your balance on the $50 you want to withdraw. You might have less than $40 left.
Even if we use viabtc, some say it's hard to keep up because it seems like there are a lot of people waiting every hour that passes for the first 100 to submit a free submission. Just yesterday, the bitcoin fee was so high that it reached 40 dollars. It's shocking.
