I believe this will be hard to accomplish now and that's because there's a proliferation of altcoins. In the past, there weren't much of altcoins and the funds that flew to them after investors redirected their funds from Bitcoin to them was felt hugely. In today's reality such transfer of funds is shared among numerous alts which are mostly even xerox of one another. Most altcoins are fraud.

In my opinion, if anyone is looking out for the same altcoin bullish momentum of 2018, they should forget it. It won't happen. Just a few alts will see that push, not a totality of them.
