I do not own bitcoin and i dont believe that bitcoin will be around in coming years since it uses an economically unsustainable model. However, those that have invested in the bitcoin space have created a great deal of value for the bitshares community that would not have otherwise been there without bitcoin. 4000+ bitcoin that have been collected by bitshares could still be valued at $100 price of year ago. Furthermore since pts is valued in btc the price of pts would be significantly lower as well. Some times irrational exuberance is necessary to get industries off the ground. Although bitcoin and altcoin investers allocations of capital may have been misguided, it does not mean that they have not contributed to bitshares indirectly.
