Here you can clearly see that that total received bitcoin was about, but he spent more than 200 i guess...

Can someone explain how is that even possible?

Answer 1

Whoever who made these transactions had other sources of funds than just the account you queried. Thus he was able to form transactions that delivered more funds than that one account received.

If you total amount delivered by all of the transactions that drew from that account, they do total more than 200 Bitcoins. But those transactions drew from many accounts, not just this one.

For example, if you look closely at transaction ce99101a40bcf2bceab57ac43ff881260a6961c546b9d52e0737ed6acd39a43a you can see that while the transaction delivered over 25 Bitcoins, it had numerous input accounts. Only 0.1528 Bitcoins came from 14f4WdcxkRhP2N5JbCWe3q7QcNtDiX82ba.

Note that this is perfectly ordinary. Some wallets behave this way automatically, constantly generating additional accounts to hold funds and managing those sources as a unit, forming transactions that draw from several of them and returning unspent funds to yet another new account.
