It's not that hard to place an order every day, so why are so many people struggling...
1. Check the number of transactions in the last 24 hours; high liquidity is key.
2. Look at the trend; an upward trend is always a safe bet.
3. As long as it's moving positively, just run with it; don’t hold onto it. This is for earning points, not for trading coins.
4. Don’t buy with your eyes closed; check the slippage and fees before buying. There’s always some fluctuation when buying each coin.
