Daily $1 is not suitable at all but daily investment is a good way to gather money. It is really a great habit for investors. We can make it monthly from daily. Hopefully it saves our daily fees and time also.
What is the ideal minimum amount for daily or monthly investment in your opinion?
I think $100 is a good investment monthly and don't do it every day because the fees is too much for that and if you do this for the next 5 years, you might ended up with a lot of bitcoin at a very expensive value because many believes that bitcoin will continue to reach highs when the time comes. I also suggest not just to hold bitcoin but also know when to sell your holdings, because bitcoin will always go up and down in the next 5 years.
