I'm also interested to know holder's opinion. I think, along with miners, holders are also a pillar of the bitcoin economy. Especially, this type of poll offers a chance to almost anyone in the bitcoin economy to participate.
True holders have Bitcoin in cold storage and will not take the risk asociated with this. At least not me.
The problem is not solve because we will increase temporarily the block size. Again we will se mining pool to create empty ro 60% empty blocks and again we will have spam attacks. The only good solution will be segwit patch but and this is not enough.
Bitcoin because the most popular cryptocrurrency is and the first that need to solve this capacity and spam attack problem
I like to ask how this increase solve the problem when pools will continue create the same block size and with maybe less because they will have less fees? Blocks create every 10 min and this is not a Blockstream evil decision.
Give miners ability to create unlimited blocks and no one will complain they just creating 1-5 MB blocks because the fees might be not enought for the risks for the increased orphan rate and losing the base 25 BTC. Increase the fees and they might mine ever slighly bigger blocks if it makes economic sence. True free market at work, you wont find more economically effecient method with artifical limits, central plannig is never more effecient over free market, economy 101.
