Hi all,

I'm looking for a way to start doing some proper crypto analysis.
Specifically I am looking for:

• Good software to show charts
• A place to get historical price data from

Tips anyone?

As reported here, Huobi and OKCoin suspended Bitcoin withdrawals for a month (starting 9th February).
I have never used Huobi and OKCoin, but I'm wondering: What does that mean?
Are people with BTC in their wallet on Huobi/OKCoin not allowed to trade it back to CNY/USD anymore?
Or how should I interpret a "Bitcoin withdrawal suspension"?
