The last point you list is main reason I hear new comers struggling or people who have money will not invest in crypto. There has to be some sort of way to stop the scams if more investments would flow into the crypto market. Just because it is the latest and greatest does not make it the most valuable. You look for example Japan's tech companies. I would not have thought Sony or Toshiba would be struggling as much as they are now against competitors when they were at the cutting edge of electronics. Yet people stop buying their products and went some where else. All be it not a good example to crypto market but what I am trying to get is even if crypto is good with out the security and protection in place the lack of users will mean lack of money.
