When people are buying crypto they should just assume the money is dead and gone and ignore the price afterward. Same with gold and silver. Even lock it away if tempted to sell. Since bitcoin hasn't gone to zero, and since real bubbles (with no underlying value) don't recover from popping it is safe to assume that, where as there is plenty of speculation in the markets driving crazy price swings, the overall trend is definitely bullish. At least imo. But I am not a professional, nor should such be construed as any kind of advice worth betting on- just an opinion.
