I also prefer to invest in coins in the top position. In my opinion, the top coins are more potential to bring success than coins that are in the bottom position. Indeed if the situation sways then all coins will also sway, if the top coin has decreased in price then of course this price decline is also followed by coins in the position below. Although at least not necessarily successful but the percentage of success of the top coin is higher than the success percentage of the bottom coin. I still need to learn a lot to determine which coins can survive but usually coins like ethereum, ripple, and litecoin have a higher percentage of success.
