Lost 25 BTC by sending to what I thought was my instawallet... But it wasn't. Instawallet is just a bit richer because of my stupidity.
Lost 20 BTC by sending to what I always considered to be ~davout's wallet...like every instawallet. Hoped he and his had the skill to keep them from getting stolen (what with his mainstream bank operation and all) and the integrity to not steal them himself. But hope is well known to be a lousy strategy. I hope now that he can get them back on-line and under my control. If not, I never relinquish control of more BTC than I can afford to lose and chuckle about a bit in the process.
The 50-ish BTC I sent to my instawallet as pocket change were worth about $150 worth when I put them there, and it has been quite convenient over the 1.5 years. The 40-ish remaining suddenly became worth more than I wanted to chuckle about losing so I sent half to Mt. Gox a few days ago. Lucky timing.
Instawallet made it a point to advertise as being for spending money and had only modest security. That was front and center on page...or at least it was at one time. I've go no complaints about losing it, but ~davout and crew need to accept their black-eye like men if they end up losing these funds. He is not shy about calling others out for being clowns. OTOH, I've not seen much from him lately so he is probably either really busy...or retired comfortably in the Bahamas.
