Background: I started to post a daily PSA in the Monero trading sub after collecting circumstantial evidence within the community for 9 months. The observations made regarding XMR should (at least to some degree) be applicable to other cryptocurrencies as well. Don't say you haven't been warned.

Likelihood of the most important centralized exchanges (CEX) running fractional reserve schemes/scams:

Extreme high

• Binance
• OkEX
• Bitfinex

High

• Poloniex
• HitBTC
• CoinEx

Unclear

• Huobi

Low

• Kraken

Advice: Get your coins into your own wallet asap.

Always remember...

• "Not your keys, not your coins".
• "A fool and his money are soon parted".

Don't be that fool.
