Bitcoin can be alternative that provide income to people who are always online in the internet. Just like joining here in the forum there is an opportunity to earn bitcoin when we join signature campaigns and when we had our payment we can hold it and wait for a year or two its either the coin will have a higher value or lesser but holding is worth the wait. So we need to be patient here to earn income.
very precisely because here we use is to buy at the bottom price and sell at the top price, to get the price difference is the advantage that we will get when applying such a way, but if in a state of need then legitimate right to sell directly from the previous work
