1. General warning
Trading crypto assets is a high-risk activity and is not suitable for everyone. Prices can fall quickly and you can lose part or all of your capital. Past results do not guarantee future results, and no figure published on this site, including user opinions and the calculator, is a promise of profit.
The risks below can also combine: a market fall during an exchange outage, for example, is worse than either on its own. Neither previous experience nor technology removes this risk. If anyone, a manager included, suggests otherwise, do not take it as a guarantee: it is not one.
Recommendation: invest only money you can lose without affecting your basic expenses, your debts or your emergency fund.
