So... January 5 to February 2, yet another period in which BTS will not go up, because the bitshares community is spending their money on yet another crowdsale instead of buying BTS.
You are missing one vital fact....
ANY development that is made and works with the BitShares PLAY Chain will be easily transferrable to infrastructure that can be used by BTS. So your point is actually kind of wrong. If we had a 1000 altchains each with only a few serious Developers, they would still be essentially working part time for BTS, free of charge.
This isn't even talking about the HUGE demographic of future BitShares Users that PLAY could funnel in after it has grown enough. I am constantly floored by how many people see devs who want to build infrastructure for DPOS (just not under the main chain) as a threat. I see them as a blessing--ESPECIALLY if they are sharedropping on us.
