For beginner traders.
Often, small traders mistakenly think that trading is simple and not risky.
For example, in trading, it is not necessarily when you buy, then sell, and then buy again at the same value as the previous transaction.
The transaction is buying and selling.
This means you buy a currency against a stable currency and then resell it.
This is considered a transaction; after this transaction, if the price of the currency increases, you buy at the existing price because it is at the same value.
For example, I bought at the time $BTC
for $16,000 and sold it after a while for $25,000, and then its price increased in the rise. So, according to the principle, I would buy it for $16,000 or less. This is impossible because its price now is 118,000.
