1$ is too low but according to the basic rule "" don't invest more than you can afford to lose" i think its very good because monthly your investment will be 30$. here i will give advice that instead of adding 1$ daily, it will be good option to add 30$ monthly. if you buy with credit card, it will cost you daily. if you choose monthly deposit then you have to pay only one time fee for depositing.
Buffett would not agree with you, because he invests very large sums, but at the same time he is definitely not ready to lose them. We create savings and invest them, for many of us this is a lot of money, especially if we are talking about a long investment time, which can take several years.
To begin with, these will not be very large amounts, but over time we can increase them when our income grows. Therefore, investments will always be those amounts that we cannot afford to lose. You need to take care of their safe hold, and think about diversification when investments reach large values.
When investing, no one wants to lose money, especially with large amounts of money, but in investing, there is not only success but always risk, so we need to have backup plans. I have not seen anyone who has never failed in investing, even billionaires, or veteran investors like Buffett, at least they have failed a few times, but it does not make them bankrupt or down.
Always have an investment plan, and diversification is essential, and I would like to reiterate that no one wants to lose money, but the future is unpredictable, so never invest money that you cannot lose.
