Need to move coins from a paper wallet to poloniex, but no time to sync whole blockchain, what is the best way that I can do in a couple of hours?
install an SPV wallet like electrum (you will have to download less than 100 MB in total) import the private key and spend. but your computer has to be clean if you want to import the key on it while being connected or have been connected to internet.
there are other ways of doing it offline like making a raw unsigned tx online and singing it offline with private key but that takes a longer time and needs more work.
Thanks, would love a tutorial on how to do the offline signing method
