Do some research seriously before you decide to invest in any project, you cannot just invest in any random big altcoin in this crypto world. Atleast you understand the project, what project/services they offer and the team behind the project, so even though the project doesn't match your expectations in the future, at least you've tried your best to choose the right one.
and also read and find out what projects were featured at that time, for example when it was summer people would buy ice cream instead of drinking hot drinks.
