Never use bittr when you urgently need to send bitcoin somewhere. Only use bittr for long-term savings where confirmation time is not an issue. Please be advised that due to bitcoin's decentralized nature, a mining fee is necessary to incentivize the bitcoin miners to safeguard the network. Bittr broadcasts bitcoin transactions with relatively low mining fees. The more congested the bitcoin network gets, the longer it will take for bittr transactions to confirm. However, our transactions are not broadcasted as a single transaction. Instead, we will always be spending the (unconfirmed) change from the previous bittr transaction. Because of this, all unconfirmed bittr transactions are stacked upon each other, improving the likelihood of them being confirmed all at once. The more unconfirmed transactions being stacked upon each other, the more interesting they become for the miners to include them all (accumulating mining fees). In the unlikely event transactions do not confirm in reasonable time, we can always send the remaining change with a high transaction fee to ourselves, this technique will ensure your transaction will always be confirmed at some point and never gets “stuck”! This method is also known as Child Pays for Parent (CPFP).
