Your views are very naive, I don't understand how can someone be so pessimestic if its about the value dip its nothing but corrections and all the disscussions about bitcoin being just a bubble are bullshit. As for the technical and dev side of things, bitcoin is getting great updates coming its way with the implementation of the lightning network.
You are right, clearly this person is not interested on actually research what is being done to improve BTC and just whine and wish BTC falls
You are not right. I am aware of developers working on solutions, but you can't deny that developers of other cryptocurrencies do a better job doing so. Other cryptocurrencies have a higher tps for example.
Off course you might feel bad by reading posts like mine because you are a fanboy
