See the value of the altcoin index at the moment and you'll understand that we are now extremely high so i would not expect further growth and would start fixing profits right now.
I agree. Despite the lowered dominance of bitcoin, I also think that we are very high. And perhaps the current correction is the beginning of a long downward movement, or even the beginning of a bear market.
Although I do not think that large funds would have made such large purchases before the start of the correction.
Many large funds buy Bitcoin. I agree. But cryptocurrency must be useful and not used only for speculations.
There are many ecxhanges and a lot of traders earn money on cryptocurrency.
Now tools for trading are actively developing. For example
https://www.qoiniq.com/ allows to trade at the same time ant different exchanges and with different assets.
More simple and convinient tools for trading more traders use them.
You say that cryptocurrency should be useful and should not be used for speculation, but at the same time you give a link to an unknown cryptocurrency exchange or terminal that allows you to do just that, speculate on various cryptocurrency rates. Understand what you think and write without contradictions.
