Are there any bitcoin transaction limits?

There are no limits on how many bitcoins you can send or receive as there are no maximum or a minimum number of bitcoins to buy or sell. For security reasons, very large transactions (from 5 BTC and more) are processed manually, therefore there might be a delay.

Bitcoin transactions outside of SpectroCoin cost 0.00075 BTC. Transfers to other SpectroCoin users by email or Bitcoin address generated at SpectroCoin are free.
