There are always threads on the forum referencing the following
This is the best year to join crypto currency
This is the best time to invest blah blah
There is no year that crypto currency won't make pple smile (profits) and cry (losses), simply because crypto currency cannot make everyone happy at the same time.
There is no year that is the best to get into crypto currency, there is no indication for the right time to buy or sell, everyone just do at their time when the feel they have make enough profits or cut their losses.
