a very big opportunity occurs when the altcoin price drops, you can increase your investment with the remaining capital. the price is very falling. You can get a huge profit when the price returns in the future
Sometimes a drop in the price of a particular altcoin indicates the downfall or the end of that coin. I invested in a coin when its price dropped from $0.70 to $0.30 with the hope of making huge profit if the price should go back to $0.70. As at now, the coin is just worth $0.004 and i lost about $500 out of my initial investment. Not every drop is an opportunity, some might be a death trap to your financial investment...
If the drop happens with promising coin and it can go back later but the problem is the performance of the company just like speculation. That's even happened in my life. Investing in the coin that drastically dropped anytime.
