So, this has been rounding my mind for since i started to believe in crypto.
I there exists plenty of wallets and various types, but this is a questions focus on trading wallets, and dealing with exchanges.
What happen when you are not using a wallet provided by the exchange (eg. Bittrex), but then you want to sell a coin the coin ASAP so you dont miss the peak.
HELP!
You have to transfer the funds to the exchange that has the coins you want to buy. If you wait for the last minute you may not get your funds onto the exchange quick enough to get the new coin at a lower price. Remember, the transaction will need several confirmations before the transaction is considered complete and the funds exist to be able to purchase another coin.
