This article is somewhat misleading. First of all, adoption hasn't "increased by 30%." What has happened (until recently) is that more funds were allocating a portion of their investment to crypto currencies purely as a speculative exercise based on recent past increased in the price of the coins in question. This serves to reveal the real problem with crypto: it's a purely speculative vehicle, like NFT artworks. No one is actually using crypto currencies for real-world transactions. Therefore, crypto will remain extremely sensitive to investor sentiment because it has no intrinsic underlying value nor utility. This means that eventually, all value will evaporate. In the meantime, however, some may indeed profit from getting in (and then getting out) at the right time - just as is the case with any other bubble.
