I'm a believer that Bitcoin will be rise still over the next 2 years passing 100k. That being said I really don't think that Bitcoin will be used for microtransactions for most people due to the fees and slow speeds but I think it will be primarily used to hold wealth and therefore the value will pretty much always be there and still increase slowly over time. Projects like Iota and Cardano will eventually replace the hype that is surround Bitcoin due to their usability and innovation. Just my thoughts, I'm no expert though.
