If you don't know how to grow your bitcoins than just hold it for prices go up. But if your want your bitcoins grow then you can lend your coins on this forums with proper collateral then you slowly grow your coins over the time. Some of your coins you can invest on casinos bankrolls. These are biting high risky investments, but surely you will earn a good profit over time because in most cases casinos are the winners at the end.
That could be an ideal to do if your holding huge amount of money but what about for people who have only little bagged of btc in their wallet? Maybe its not advisable since the wait is not really worth for low budget peoples so thats why they should find good thing or programs that they can earn money maybe investing in casino will be good but let's think also the the risk so we can avoid some lose from it.
I agree that holding a small amount of BTC for a long time is not worth the wait. If you really want to have a big profit but you have little btc, all you can do is grow it by involving yourself to bitcoin activities like trading, product selling that involves service and goods, joining signature campaign and other stuff that can earn you bitcoin.
This is the first step of growing the coins that you earn more than your needs so that you have savings that can be invested for growth. Once you have half a btc minimum, you can invest it in altcoins trading and can get reasonable profit.
Although the profit earn from trading will not be much that you become millionaire, but still it will keep on growing your bitcoins if you wisely buy and sell altcoins.
We need to be more wisely enough for us to save more money when we earn and save for our future.
In this signature campaign it can also help us grow our btc and if we use our btc wisely we can earn more money by saving it.
