But they do not and will not move, as all the institutional money is pouring into bitcoin.
We won't see a "year of the altcoins" for a very long time, at least not before bitcoin has reached one million.
What do you mean? haven't you seen the meteoric rise of Ethereum as well? Or ADA? Or Polkadot? or even BNB? Time has change, even if bitcoin's dominance reaches $60% or higher, still altcoin market can be in the bull run as well. And then we have the whole defi as well, billions of dollars are being lock for staking. So I guess you need to look and investigate further before you claim that we will not see a year of the altcoins.
Of course I have seen the meteoric rise of some altcoins, I am invested in a few myself and have made great profit.
But this uptrend is stalling right now and new money is needed to sustain this rise.
But at least for the moment it seems that the big guys have chosen bitcoin. I myself hope it will change with coins like XLM, but I admit I have my doubts.
