Just wanted to say that a few minutes ago I made my first ever alt crypto trade and it was so damn speedy. From getting the BTC balance to reflect on my poloniex account to then withdrawing into my Bitcoin wallet, all took less than 3 minutes I would say. Normally I would have kept my BTC in the exchange for future use (although not for long periods of time) but I wanted to see how all of this goes down first as a n00b.
You have a good thing going here, busoni. Keep it up!
If you are reading this and aren't using Poloniex.com yet, get to it. It can become something big soon.
Most people have the same experience of Poloniex as you do but unfortunately a lot, and not just a small %, have very bad dealings with Poloniex, where (when depositing or withdrawing) having your coins stuck in transit for several weeks, if not months, is not an uncommon occurrence.
If you want a reliable exchange go for Binance, they are one of the top exchanges for reliability and great customer support.
I wish they would accept Clamcoin.
They require "Coin CEO's" to sign some NDA, but CLAM doesn't have that shit.
