I heard about the bug a year ago. It was fixed, though.

The fact that bitcoin is mined with ASIC hardware is not so important. As to the miner attack, the fact that it happened and failed was a very positive thing for BTC.

On-chain transactions do not need to be very frequent for Bitcoin to have high value. And Bitcoin does not need a marketing budget. EOS may have raised four billion but its market cap is still dwarfed by Bitcoin, which still worth over a 100 billion.
