volatility of BTC do the job (nightly, usually).
if you are lucky ... bear or whale test the high/low trading of the exchange and you can earn like 2 BTC in 1 night.
But trading is dangerous, risky, and highly profitable, be careful. Easy to be broke or rich, haha
Every strategy always have a risk. The problem is which strategy are we gonna use to minimalize our risk and get good payment. Because if all of them sure got risk no matter it is high risk or low risk still you have a risk to loss your bitcoin
Its true that keeping your coins in your wallet is right thing and the safest way but keeping in your wallet wont get you anything from it, why dont you try to do trading with bitcoin or altcoin. That is a real helpful to earn some of your bitcoin
The first thing you ask people to save their money and invest some in bitcoin and now you saying that people withdraw things to spend on their unuseful things? So when will they save their own money or bitcoin if you guys keep on spending on that unuseful things?
