He could be right, 100k isn't a huge jump from where we are right now, it may seem like it is a long way away but it's only 6x the price. 50k Will be a big hurdle to overcome and then 100k. The question really for me is, will bitcoin crash before reaching 100k. I do not see any scenario in which the price stays stable under 100k. It will either reach 100k or it will crash beforehand but if it doesn't crash in the next 1-2 years then 100k will happen almost for sure.
A 6x jump in any asset class is a huge increase. You should also note that Bitcoin's price has increased by 15x this year. Lightning usually doesn't strike twice at the same place in quick succession.
These kind of sound bites give the trader some quick and cheap publicity, nothing more.
