There will be a time that people will get tired of the outrageous fees of bitcoin and it will rise more in the future so I am sure that either IOTA or RAIBLOCKS will be the choice for mass adoption.
no not all of them will be tired in bitcoin even if the fees were too high but as long as bitcoin is still profitable there were still people that are going for it and also most of them doesnt actually use bitcoin as a form of payment method rather they are just using it as an investment or for trading in order for them to earn a profit however some people that using bitcoin as a payment gateway are now slowly moving on to some other types of coins like the ones you mentioned above in order for them to avoid high fees and slower procsessing time.
Since opening this topic, you are the one who satisfies me the most. Unfortunately I have no merit to donate to you. Please pick up my words: "Thank you very much!"😊
