Forget about me for a moment and put yourself in my shoe, I am sure there are family men and women on here, what will you plan to do if you are in my shoes right now?
Honestly I will diversify. Since we are talking about established financial status through Bitcoin alone here, it would be best to add more investment besides Bitcoin.
We cannot say what the future holds, Bitcoin might soar in an imaginable height or Bitcoin might become stagnant or worse get dumped. It is always best to have a backup plan, or something that can support us when one of our sources of income fails to deliver. Aside from that not all years is a golden year for Bitcoin, so during those times of hodling, we must make sure that we have the other means to support our daily needs.
It is not bad to be a Bitcoin fanatic, but it is is always better if we have alternative ways in bringing profit in our table. This way, we can make sure that the future of our family especially our kids is well supported by our income.
Haven to decide on verging your investment on Bitcoin alone can be risky when you don't diversify. Even if you have to split your Bitcoin assets in different wallets, you are still not far from same market surroundings rather you are accumulating your Bitcoin assets.
You really need to spread your investment away from Bitcoin otherwise, you will be on-chain in a particular source which you can only make profits in the same market events like your probability of making profits is pinned down there but it you diversify, you can Perhaps earn from different investment opportunities according to your diversification in respective that the crypto markets has it market events as the coins varies.
On a sincere note, investing on Bitcoin without diversifying may not be an easy success to achieve your goals when you have only one source hedged on your investment.
