Can someone make for me rough forecast for the Shiba till the end of the year. 
Why do you ask this question knowing that no one has a crystal ball? don't take people's forecasts as investment advice, in this falling market investing in this project can be dangerous mainly because it seems to be a project that increases a lot in price thanks to manipulations, I've seen advertisements for this altcoin on pornographic sites, that's the bottom of it
It's likely that it has ended already its surge but there could be recovery still for it.
And adding the fact that when the price of bitcoin starts to drop it drags all altcoins away, it's definitely not a good time to buy that altcoin.
