There's reasons for this pump (Constantinople pumped ETH, Coinbase releasing BSV pumped BCH) but we're gonna drop eventually so you can count this as a trap.
Yes, I expect this market to dump again because this is just a temporary hype and if something bad happen again with the hardfork of ETH people will panic again. I must say taking profit right now is good, and invest again if there's another bottom. Short trading might be risky, but you can earn a lot from this.
