Honestly, i have followed lots of twitter influencers and i can say that most of them are active during bull market and goes silent when the market is dull. you see post like btc pumping, lets go to the moon and so on whenever the market turns green. looks like most jump out from Nowhere to proclaim the BTC goodness. My opinion, if they failed to inform their followers and listeners to be careful and never to be greedy, then they are not truly crypto influencers. all they wanted to do is dump on their fallowers and move on.
My belief is that whatever goes up will surely comes down and btc and other crypto will correct sooner or later and we might wait for months again before another major outbreak like we are experiencing now. Do not go all out on BTC.
Influencers are very important to a project, influencers are a marketing strategy so it's only natural that the coins / tokens promoted by them price will pump.
but not all influencers can do that, depending on the influence they exert on their followers on social media.
be careful don't be easily attracted, it doesn't mean the project they are promoting is Legit.
Indeed it is very important but the question is, as an investor do you trust them? I am hesitant to say yes because lots of them are being paid to advertise a certain cryptocurrency. After knowing Mcafee, I never believe anything what an influencer said unless I do a research on them and study that cryptocurrency.
