transfer coins number limit > 50 million

Current QT wallet (either linux or windows) can not send coins larger than 100 million in one transaction. This maybe due to Litecoin limitation where NENG forked from.

Noticed today that the limit could be no more than 10 million in transfer of mined coins. The warning was the transfer data size was too big and transaction can not be created in QT wallet on 20 million NENG. Smaller size of transfer 10 million worked.

Math behind this issue is actually complicated. The upper limit varies depending on source of sending coins. For those CPU or GPU/ASIC solo miners, the sending of those mined coins has limit of between 10 million to 20 million. This is mainly a limit of 1 MB block size. Mined coins have multiple addresses with 20,000 NENG each. Therefore, somewhere between 500 to 1000 addresses combined into one transaction will hit the limit.

Another related limit hit ShorelineCrypto exchange. Some users had large multiple deposit (close to 90 million) continuously and the exchange software can not credit balance automatically. The exchange software works fine on smaller deposit. When it is large, the "move" command hit limit and failed to work. This is related upper limit similar to "send" coin limit.

From the past experience, withdrawal from exchange equal or smaller than 50 million NENG worked. For larger withdraw, 50 million NENG one at a time. Only withdraw next 50 million after prior 50 million NENG also worked. This 50 million NENG limit is another kind of similar limitation in NENG block chain.
