I've been holding my altcoins for years now and waiting for bullrun to make a better come back but I'm yet to be confused that this is the real bullrun since many altcoins don't bother favouring from the bullrun,what is going on?

The capital in market is almost focusing on Bitcoin because everyone all want to have as more Bitcoin as possible to wait the extremely raise of Bitcoin when the Bitcoin's halving happens in 2020
The price of bitcoin right now ranging from 2017 to now is in mid range. I suggest to accumulate more bitcoins because we don't know exactly when was the time to rise again. But its better to be prepared.
