Crypto is at another rally. I heard that 2018 will be the GTFO year where BTC will hit 20-50k, maybe? Or some McAfee levels... Who knows. And then it crashes and will be low for quite some time. But what if the crypto will be just calmer. Go a little bit up, then down and stay on pretty much the same levels. What if there will be no bubble. Or what if the bubble already burst. Opinions?
