I only buy a major coin because it was more trusted but I also hold some shit coins from airdrop or bounty, I knew the value is worthless but I had no choice but to keep it and hope that sooner or later it would be worth.
Major or minor have the same result when it was facing the bearish trend. Even bitcoin does it dude. We have shitcoins in our wallet and it caused by the bearish trend that makes us being trapped at a high rate.
The reason is to get back our money in the future.
