It is obvious you fails to understand the reason for diversification. Diversification is not a means of acquiring or making more money but rather the purpose of diversification is to reduce risk by investing in different assets. I don't really see anything wrong with the idea of investing in bitcoin alone more especially if one don't have the financial muscle to diversify or spread his assets across different investment in other to reduce risk
This idea of diversification have ruined many people because they never knew what diversification really is and how to apply it. You can't buy Bitcoin and shitcoins and call that diversification, instead, that is a financial mistake. Diversification should be Bitcoin with other areas of investment probably physical investment of an entire different area like stocks. This will work somehow even though I still believe that an all in on Bitcoin still remain the best since I have not seen any investment asset that have done more than Bitcoin in the last two decades.
Instead of discussing diversification, we should be talking about consolidating our investment in BItcoin especially now that there is a minor correction in the market which represent an opportunity for a good buying position. This will do us more good than discussing diversification that can make people think that spreading their money to shitcoin is a good practice under diversification
