I'm really interested in those statistics , can you provide a link for it:?
Also , I don't give that much tought for the rest of your claims
.
http://agran.net/bc_getbalance.php?top=100I think the top few are MintPal cold storage wallets though.
Hmm , let's hope not. If a single exchange hold that much , i'm having mtgox nightmares
I don't think you have to worry about that really... but again - if you use an exchange as a wallet, you're asking for trouble.
On the other hand for an exchange with thousands of accounts to have $2M-3M in the most widely traded coin on the site is nothing. I would guess a few of the other top ones are Cryptsy. Just think about it - if there are buys (and sells) of 100-200BTC occuring on MintPal - then the exchange has to have
both 100-200BTC
and 100-200BTC worth of BC on the exchange at the same time. Of course this is simply for these two trades to occur, and obviously they also have all of the BTC and BC represented in every other trade. What was volume yesterday? Naturally, there isn't that much there as traders move back and forth... but probably a third of the volume is/was stored in MintPal wallets at some point in time.
I only keep what I trade with on there, but it's big enough that just ~2000 people keeping the same amount would fill up those wallets right there... and I'm a tiny minnow in this ocean of whales now.
