The wisest way to benefit from your bitcoin portfolio is to hold for a very long time and continue to DCA.
Indeed, holding Bitcoin for significant period of time and consistently adding more Bitcoins in your portfolio by employing Dollar cost averaging strategy (DCA) is a prudent approach. The historical performance of Bitcoin has vindicated that it has potential of substantial growth and ability to outperform other class- of assets, including gold and stocks, in the long term. However, decision to continue holding and acquiring new Bitcoins entirely depends on individual's financial situation and circumstances, additionally there is always risk associated with all type of investments including Bitcoin, therefore it is wise to carefully evaluate your financial situation, long term goals and risk tolerance before making any investment decision.
I think thats actually the first thing that should come to light with anyone who is currently planning on starting an investment be it bitcoin or any other type, because you can afford to invest more than what you don't have and especially if its a long term investment it is going have a great toll on you that might result in you tempering with your investment or selling of a portion of it because of the pressure of not having enough funds to keep yourself sustained, so I will prefer before going in for an investment plan one should properly evaluate all the necessary risk involved and know the capability of his or herself because tangling yourself all in the name of saving up some stacks.
Its better to go for an active plan where you can be able buy a little fraction of BTC or save up something from your little earning, I think money splitting can help thats split it into sections where you can put some in your investment and still not be affected.
