Well this is just a speculation and there is no guarantee or certainty in what Joao said and if he said Bitcoin will reach $140k I won't doubt this one because Bitcoin almost reach $130k some weeks ago and so this one can be possible but dipping to the extent of $50k sounds somehow to me and I can't believe that even though I'm aware of Bitcoin volatility. You can accumulate or buy Bitcoin at any price especially if you are using the best strategy (DCA method) and so i would advise you don't lean on speculation because is more like a guessing or prediction which most times doesn't come to pass, so accumulate your Bitcoin and also prepare for any opportunity that will come.
