I consider that a good investment at all valuables including gold. As well as real estate. You can buy houses and apartments abroad, and lease.
Yeah, you're absolutely right, business or the most profitable investment is an investment in a period that has been or is often done by everyone. as investment gold, land, House, apartment, or other investments. But keep in mind the things discussed in this thread is an investment with bitcoin, so all that you mention I think can not be done using bitcoin. And in a very profitable investment bitcoin is to use the system to sell and then buy. Sell when prices are high and buy when prices fall
For me or maybe for anyone the investment in gold and in houses/apartments are two different places as when we invest in gold then we will not be sure that how will be the price increase and when will it happen but if we invest in buying any house then we can easily give it on rent and so we can get a permanent and regular income from that house.
