$BTC remains the best bet so far. However, like any cryptocurrency, it is necessary to take its volatility into account to avoid losing money on the investment.

Now, what can be done to earn bitcoins? One option is to accept payments in that currency and others, participate in dynamics or games that offer satoshis as prizes.

In short, the best thing is to wait for every opportunity to increase your savings and have a good extra to get you out of any bind.
