Bitcoin new user question

Hi all, I’m new to the trading of bitcoin and wanted to familiarise myself with a few terms. Firstly, I keep hearing about “leveraged strategy” vs “passive spot exchange funds”. What does this refer to? Secondly, what role could AI play in improving bitcoin creation/adoption? I keep hearing that bitcoin as a whole is independent of AI, but something tells me that’s not actually going to be the case. Lastly, with recent news of price crash predictions (personally I think it will crash and then lift substantially) what is everyone’s current purchase strategy - continue purchasing/ continue purchasing more (as the price goes down) / delay purchasing or invest in altcoins until bitcoin resumes normal pricing. Thank you
