Those who had invested in altcoins can now sell them at a multiple profit. Along with the increase in the price of Bitcoin, all the altcoins have increased in price. If we invest at the right time, we can get profit. We will not be able to make profit but will put our invested money at risk. So we should always find the right coins and keep investing.
Apart from having to be able to find the right coin for investment, you also have to be able to find the right entry point and the right exit point in order to get multiple profits at a certain time or at the time as you said. Because what we often see now is some people who know the entry point more precisely but don't know the point to exit and take advantage of what they have bought before. So the level of profit is not much higher because they have gone through a better moment to get out of what they have done before.
