AML, banks restrictions, big data, proof of funds, laws created to either limit you or something else...
Illegal activities using cryptocurrencies, this excuse is fake like Santa Claus is.
By the way, speculating and investing isn't really the same thing
The philosophical question: is the finance industry at the service of society?
I believe in order to see Bitcoin adopted massively the population needs to change its mindset about money, how we use it and how the finance works nowadays. Because there are fundamental dysfunctions in with consequences economic, social and societal. If we reproduce the same errors then we will just duplicate the same problems, another disguise but the same shit, instead of to be with fiats it will be with crypto.
Or maybe Bitcoin will be the 'tool' that will make the population changing, in case of a monetary reset or something like that.
By accepting to be regulated, it's already the beginning of the reproduction of the same errors. I would like to remind you how many times we have read here "Sir, regulations will help the mass adoption and institutional money"
Institutional money, oh man we don't need that, we don't need regulations, Bitcoin has been doing well without.
Just because regulation exists, that does not mean that people are advocating for it.
Of course, there are various forum of bitcoin and practices that are cumbersome and anti-thetical to bitcoin. but there is so much that any of us can do about systems that are built and the willingness of people to use them.
Just take, for example, people getting into bitcoin and keeping their coins on exchanges, how are you going to stop that? There needs to be other options in order to incentivize people to use the other options.. Also, remember local bitcoins? Hard to use local bitcoins anymore, so are other direct systems developing? Maybe ones that are NOT as good, but there are some developing and likely to continue to develop.
You can assert that speculation and investing are NOT the same until you are blue in the face, but the fact of the matter comes down to actual practices, thinking of people and ways in which people might get into bitcoin rather than getting stuck on definitional assertions that don't mean much of anything, except some academic or theoretical claim regarding how a word should properly be used - which means diddly squat to me.
In the end, bitcoin gives you an option that you can choose or choose NOT to involve yourself into it, and you can choose whether you want to use it or hold it and if so, how you want to accomplish those. Decisions regarding involvement in bitcoin are going to vary, and sure there still remains some technical difficulties too, and maybe if the lady in the small village hears that she can buy $10 of bitcoin per week and store it on her phone in her lightning wallet, it will keep value better than her local currency, and she should be able to use it one year later or several weeks later, she might be willing to buy a bit of it to have, just in case it might come useful to her in the future. Of course, user-friendliness is helpful and also possibly having a friend who has already done it can show her how to do it, too. That can be considered using it, but it could also be considered storing it for future use, and choices like that are going to vary - and might also depend upon what kinds of other value storage and/or transactional options are available to her.
