OK, but can anyone in this topic assume that actual utility in the Lightning Network for users’ regular transactions is increasing? What is Bitcoin used mostly for? Sending to exchanges for trading, gambling, buying illegal drugs in the dark markets.
i can assume that... 
any source for the bolded sentence in the quote? or do you assume too?Then, in your assumption, what is/are the utility/utilties that Bitcoin is being used best, and the highest, and can you say, or actually see that offchain transactions through the Lightning Network are increasing in those use cases on a monthly basis.
