I think altcoins bull run is a hoax. Btc is the main indicator of market and market moves as per it's direction. When you see BTC moving on the up side alts too will follow soon while if you see it moving on the down side they will rekt soon.
This year, this is how it happens, Bitcoin is the king of the cryptocurrency market and has no equal. Even Ethereum significantly loses to Bitcoin. I will also continue to invest in Bitcoin.
