It doesn't matter at what price you bought, stay calm and don't sell; Logically, it's better to buy when the market is down.

My advice is to invest for the long term and money that you won't need soon; because this way you can afford to wait in case of a market drop.

The people who lose everything or end up at a loss are because they buy when the market has already risen, or because they invest in projects without researching who is behind them, without knowing if they are scams or not.

Investing in cryptocurrencies is profitable and can still make many millionaires, just research the projects and who is behind them, invest for the long term. Success.
