no not the blockchain just bitcoin! u can use steem litecoin there or many other coins to send money almost instantly for free basically
the transaction fee increase is supply and demand, ppl are still willing to pay large fees to send bitcoin aroound the world because many only even KNOW about bitcoin and nothing else!
3$ is a large fee ?
a fee is by percent not dollars, i dunno what 3 dollars would mean , just keep under five percent
I still don't understand how much is fees in % ? last time when I sent from coinbase into xapo was about 1$ , I don't know what are you talking about ( I sent about 50$ and the fee was about 1$ so it's just 2%, I don't see any problem here )
