Ok, so today it showed me the correct amount but now it shows a message when I`m sending bitcoin
"Blockchain wallet`s cannot handle thansactions over 16kb in size. Please try splitting your transaction"
It was just 0.01
Bitcoin's network doesn't really care if you are sending 0.01 or 10000 BTC at once amount is not that important.
For bitcoin the only thing that really matters is size of the transaction.
Bitcoin transaction has these information included:
- an input - a record of which addresses were used to sent money to you
- an amount - self explanatory
- and output - addresses where you are sending your BTC
And now - if the amount of bitcoin you were sending were composed from many inputs size of your transaction will be higher (and so fee).
That is why it is unadvised to collect so called dust transactions as your fee and transaction size later will be huge.
