How can I benefit from btc? I mean let's say I bought 2 btc, what next? how can I earn more of btc or dollars
Why do people rush over btc if it's just an electric currency without having benefit from it?
Great question.
If you already have 2 BTC then simply think at what rate you have bought ? and see current rate of BTC against USD /EUR/GBP if you see major differnce in value then sell them for higher price and difference between rate will give you profit. If rate is lower then hold then till rate goes up.
Second thing you can invest you BTC in trading as you can buy other low exchange rate currency hold then with higher volumn and sell them with higher price. Due higher volumn you can get higher profit on change of rate.
Third you can invest in cloud mining . But be aware there are many scam cloud mining services are there. Cloud miningf can give good ROI.
