If you import e.g. SHIBZ and you purchased e.g. 108.977.392.383.555.560,00 SHIBZ the transaction auto-imported from the wallet only shows 9.999.999.999.999.999,99 SHIBZ
It is technically only possible to add 16 digit numbers in total including after the separator at the moment.
So you have 2 manual options now:
1. Split transactions into several 16 digit transactions at the same time until you have the full amount
2. Use "Mega" or "Giga" SHIBZ to reduce the amount digits and add a custom price to this GSHIBZ then (like some exchanges do with DOGE -> MDOGE) as described here: Entering ICO Coins and Non Listed Assets
Please keep in mind that our coin prices are limited to 8 decimals after separator. Lower prices could be shown as 0.00000000 then.
