That is very good observation and for me is see one thing that is how bitcoin is well structured and since most alts coins are directly or indirectly affected by btc, its really that focused mindset for it unlike alts coins which seems more unstable and almost all invstors run into it just to hit and run by making profits so usually become impatient for development of project but rather seeks coins on exchanges soon with high values rather than hands on board to build a reliable coin.
