Sorry for these late replies. My top 3 exchanges for alts are

1)Binance 2) Cryptopia 3)Kucoin

I'm not sharing too many trades lately. People seem to get really salty when they go in the wrong direction for them. I hodl long term, and I'm real comfortable with the coins I'm hodling. Other people want fast returns, and the market just isn't offering many of those opportunities. I'm currently sticking with anything that is well established, and has an active and supportive community, with a dev team committing regular updates to the project.
