If we invest excessively, our portfolio increases but spending every month will be burdened because a lot of money goes out to bitcoin while other needs are cut because we want to increase investment every week or month, of course this will be heavy and unbalanced people will definitely find it difficult to do this.
In as much as is good trying to accumulate a huge amount of Bitcoin as soon as possible shouldn't make us to invest excessively because at first you will be enjoying and feeling very excited with how much Bitcoin you have accumulated but however when other physical needs will arise that's when you will realize the need to have a reserve funds.
Because one of the things I understand why most people invest on Bitcoin excessively is because of the fear of losing out, because whenever they see a very good buying opportunity presented by Bitcoin price they tends to invest all they have with the hope of managing to take care of there needs from other source while all there money are being invested on Bitcoin without knowing that if the other source could not satisfy there physical needs it could lead to a serious panic that would warrant them to sell some amounts of there Bitcoin.
