You can buy bitcoin, and then wait for it to rise, you can also see the signature campaign, so that it can get bitcoin.
Holding is not a steady income for you are going to make it just like one time harvesting. So if you are going to hold today and tomorrow you are going to withdraw.
Then what you need to do is to buy again and that is not going to make you profit. For me what is going to be the steady way is with trading.
But you need to be a good trader and you know how the alt coins move.
