I don't think it will reach 20$ this year but in the next 3-4 years? sure this will because CAKE is one of the most competitive Project that exist now and may get top 10 position in those years .
so If you are willing to take this into another level? then best to keep your cake on hold for this year and the coming 3 years from now.
but if you are not sure of having this for long term then best to sell now as the market will continue dropping till 3rd quarter.
