A good investment that starts from now either small or large investment because if we start from now then later we will get used to make an investment where profits in the future will be more felt because we have started slowly from now.
Are you sure bitcoin will rise again its price from today.
See bitcoin future bitcoin has not yet approved by some countries.
People have repeatedly suggested over the last 5 years that maybe bitcoin won't keep rising and every time it proves the doubters wrong. It doesn't need approval for usage and big money is moving in so I think now is a great time to invest.
