I don't really know if Nokia has a contract with apple or has withdrawn and now affiliating with google, maybe that can also be a reason that the volume may have dropped. But however, crypto is highly in the increase and even coins not highly regarded are now increasing which helps definitely to grow the cryptocurrency market.
The categories carried by both are the same, namely about technology, but crypto currency and apple are something different,
where crypto currency is like a life in which it is a community, but apple is not a community that they build but about business,
yes this is the difference between the two , for sure you have to own crypto assets because they always increase compared to apple
