It's a great plan and I have a similar savings plan and have published it to my college friends. They were really convinced by me because the value of Bitcoin will really be very high in the future.
But to optimize your plan, you should spend about 30 minutes per day analyzing the market and choosing the price to buy bitcoin and hold over the long term. This will reduce the risk of your portfolio as well as when you need money urgently you will sell Bitcoin at a profit, not at a loss.
All this is fine. But at the same time, you should understand that major corrections can occur, in which the exchange rates can go down by as much as 20% or 30% and stay at that level for many months.
