No dont invest your savings in a thing where you can lose money.
Go for example to a signature campaign, or look what you can do to earn some bitcoins.
But what happen when you need your savings quickly? Than you sell your bitcoins and when the price go to 200 Dollar in the next month, than you lost money.
Only invest so much that i you can lose without problem.
You say you will hold it for at least 5 years, but when you invest all your invests you will look everyday at the price, and when it go down you will sell your bitcoins, because you will fear to lose money.
Only weak hands sell at the first sign of a price drop. I started buying at $500 and I haven't sold anything yet.
