About insane profits in the bitcoinsphere one may cite the Asicminer case, gone from 0.1 btc/share at the IPO to 4.6+ btc/share at the top last summer (that is a 46-bagger or 4600% yoy in appreciation not counting the crazy high dividends it paid in the meanwhile), and now back to 0.25 paying nothing but ready for another pump.
Asicminer never promised a profit. The venture was high risk and could just as well have failed, like 99% of all other bitcoin securities did. Thats something totally different as this here.
Profitable arbitration day in/day out seems not so hard to believe
I bet you believed all the pirate bullshit too? Goat's and Alberto's "arbitrage bots" ? Bitscalper, bitdaytrade, bitwhateverponzi. Havent you been around long enough to see through this? Here is the thing, even if they were somehow able to extract those kinds of profits, why would they still need your money and why would they pay the bulk of those rewards to you?
given the relatively stable differences between some major exchanges. I'm just finding strange that when such differences are increasing like in the last few days the bitcoin-trader payout is decreasing.
Oh thats easy. One has nothing to do with the other. Payout decreasing is almost certainly because the shills arent managing to get enough new users to sign up. Or did you think pirate reducing his payouts was related to anything he ever said?
