Other investments also do take time to build , rather than finding other investments to diversify on . Try looking for other sources that will help you to sustain yourself while you build your bitcoin investment, yeah bitcoin is not a get rich quick scheme so you take your time to build it well not jumping into other investments.
You have to get to a certain extent first in your bitcoin investment before thinking if diversification. Maybe then you can now think of other things you can invest on , if you start to do more than one investment at a time it will only slow you down , build your bitcoin stash first then find other stuff you can invest on .
The truth of the matter is that diversification is not a bad thing, it's a great idea, just that it should only be done when you have reached an over accumulation stage, a stage where you feels like you already have more than enough Bitcoin in your possession, that's when it feels like to try something else like investment in land, gold etc but diversifying when you haven't reach you set goals in your accumulation journey is not proper in my own understanding.
You are still misinterpreting diversifying after sir JJG has explained it several times that diversification should be done when someone has gone far in his or her Bitcoin accumulation and remember the reason you are diversifying as an investor is not necessarily to make quick profit or in short time but rather to have other assets. Moreover someone who is into Bitcoin investment is not suppose to diversify in other cryptos like shitcoins or memecoin but rather it should be something outside the crypto space since they are already into Bitcoin investment. The result of misconception can not be good sometimes so I will advise you read carefully so that you don't make mistake.
