You can find a lot of digital exchanges for trading, but I will suggest HitBtc, OkEx, Bittrex KuCoin & Binanace. These are more reliable & having a huge volume of trade.
Before choosing any exchange you will have to check that which tokens or coins you have & where can be traded.

Market is red & mostly predictions are going not hundred percent, very risky to hold some coins or tokens for long term but I hold these coins & will recommend these for long term hold.

Odem
EVX
NPXS
CS

Private key is more important although when you are going to transfer your coins into any exchange you should have to need of private key, especially in MEW private key is more important not password.

Now CoinmarketCap is working well, a sudden pump in all currencies should a internal technical fault in CoinmarketCap or maybe they are updating sites and then it happened.
But we can’t ignore hacking threat as well; there should be chances of hacker attack.

It’s a bit difficult to find a new bounty as it launch but you have to search on some sites to find it quickly, if you are very active member of bitcointalk then it will much easy for you to brows this site & will find a bounty campaign quickly…

It could be a hacker attack but should be a technical problem instead of hacker attack.
I observe only on coinmarketCap but not on any other platform or exchange.

That’s alarming to all to secure their account & password, because they can be victim as well.
For that it is necessary to use one time password along with 2 way authentication, it will be more usefull if you used hardware wallet.

To store bitcoin you can use blockchain wallet & coinbase also is an authentic wallet, in one wallet you can store your bitcoin, ethereum & BCH also.
These wallets are more secure you just secure their passwords or keys & after that you nothing to worry your assets are secure.
