Since you now know you can't use your laptop, you can save up for a desktop.

In the meantime, try some arbitrage trading to earn some money.

1. Go to coinmarketcap.com and look for a coin with high trading volume. Trading volume should be greater than $500, 000 for starts.

2. Click on the coin and you will get the names of the markets listing the coin.

3. Buy the coin from an exchange with the lowest price, then sell in the exchange with the highest price.
