Well obviously, all of those you have mentioned are true and have already been taken into consideration by most investors out there. I get it, bitcoin is not perfect but it still has a lot of time to grow and get fixes to its issues that most of us get irritated about. And honestly, I think that people have accepted these drawbacks of bitcoins, which is why they still put their money into it and hold for long periods of time. Although I know that there will always be a possibility that bitcoins will get replaced by some random altcoin out there that clearly is more better than what bitcoin is today but I personally think that it will take a whole bunch of time before this happens. Specially when we try to consider that most of us here was brought in to the crypto world because of bitcoins or have known bitcoins first before we have ever heard of other altcoins.
