Using bitcoin to buy big ticket item

Hello,

Do u think it will benefit me to buy bitcoin monthly towards a house or car?

I have 3 accounts for savings: regular savings, car fund and house fund. I put money in each month. Should I put the money that I put into my car and house fund in bitcoin, i am planning on getting a home within 3 years and car sooner.

For example, combined I put 400 each in both of them each month, should I put 600 in bitcoin each month and 100 in each home and car fund.

Thanks.
