Hey there,
is it possible to buy BTC cheaply at one exchange and sell it more expensive at another one? It seems to me that it might be actually possible.
What are challenges? Are people doing this?
Thank you!
It doesn't work always, what are the challenges in this is that you may be faced with delays of withdrawing the money from one exchange and depositing to another one.
Delay on both sides including the blockchain confirmation time, you know that sometimes it can take days if the transaction fee is low.
