The donation pot cannot collect couple of BTC for GPU development  

ASIC development costs around $10-100MLN.

The worst thing is - even if you get an investor with 100 megabucks, the chinese will steal your tech and start flooding the market with cheap clones.

I guess, LBC (or it's clone projects) should go the BTC way - CPU-GPU-FPGA-ASIC... GPU is still immature, no FPGA. You want too much.
