Where have you been lately when bitcoin fees dropped
significantly? Also, are you even aware about the on-going developments on LN? If you aren't then I do know where you're coming from thinking that the developments about bitcoin are stagnant and no such improvements are being made in the network. If you fail to understand that development takes time and resources, then you fail to see the good things behind some setbacks and that means bitcoin is not for you. I've invested so much into crypto, burned a few times but still kept on investing and here I am, making more money than what I do in my day job.
No taxes
we mined bitcoin with our pc before ASIC! so no taxes
and less physical shops accept bitcoin and that is a fact, not online store.
and many of the online shops are scammers
you can't go to shopping mall and buy ice cream with bitcoin
in 2010 that was the idea
and bitcoin is not fast anymore every one waiting in a queue and competing with a transaction fee
to be the first to validated and there is tons of other that waiting exactly like you.
it's supposed to be world currency you could travel anywhere on in the world and buy in local shops
and not only over the net.
So I guess you are just one of those people who demand a lot on something yet haven't contributed even a single thing to make matters easier.
Even if you mined your bitcoin with your own PC before and you gained something from it, it is still subject to taxes no matter how you look at it though it is still highly dependent on your government whether they will tax bitcoin or not. Also, it is not bitcoin's fault to have less merchants going in with the bitcoin train; it is their decision not to meddle with bitcoin and integrate it in their business.
Again, have you tried to send bitcoins lately? The fees have dropped significantly and confirmation times became
faster compared to the previous months.
And no, bitcoin isn't meant to be a world currency; it
can be used across borders, yes, but there's no way that BTC is supposed to replace the world's leading currency, only exist side-by-side with them.
