you should invest what you can afford to lose.
One should really invest what you can afford to lose. One good way to earn bitcoin is via investing on gambling sites bankroll since they give you interest. Also another good way is altcoin mining since it sometimes can give good profit to someone who chooses to mine a good coin. Investing in investment sites sometimes will do to just pick the ones you trust and you think will last long to give you profit.
And you do not have to be too greedy, because you can lose everything without getting even less profit than you could have done.
Yes, greediness is also applicable in investments, it is not just applicable in gambling but also in any type of investment. You need to be contented on how much you are earning with your current investment. And don't ask too much if you don't have enough money for investing, because that is going to trigger you to join some investments that are showing unreal proof of earnings and will lead you to be a victim of scam.
