Never, ever, EVER keep coins on the exchange unless you actively trading them. Find and download any and all wallets you need and keep them safely offline, just like PMs.

Convert remaining cryptos to a main currency like LTC, DASH, ETH, etc so you easily move your assets offline into a wallet if you can't find one for the shitcoins. Then when you get approved on Bittrex or Kraken you can re-buy.

I like Exodus and MetaMask for most stuff, proprietary wallets for oddballs.

Good luck!
