It is better you invest low amount of money on bitcoin right now. If your salary is $400 monthly, you can be investing like $20 on bitcoin which is 5% of your monthly income . The price is high already but there is tendency that the price might go up. If you can be patient, wait until the next bull market begins after the coming bear market to invest more. I may not be absolutely right but that is my opinion.
I think op interest increased as he noticed that price has started increasing and thus is a major interest of people because when they don't see Bitcoin at top they wouldn't have that mind to go venture to have good spot preserved for them, but however it's not too late though, even though the price has risen above expected we still believe that those who invested now would reap their profit either next year or next bitcoin halving because there could be possibility for huge dump after the bull run, and those who are not patient enough might likely panicked and sell of their holdings before the next halving.
