Lightening network is currently under testing phase and I heard that the first transaction was instant with zero fees. It has not yet been implemented officially. However, I think Segwit can save us in the meantime. Few exchanges and wallet service providers have already implemented segwit for faster and cheaper transactions. Do a little google search and you will get the information on how to create and use segwit enabled wallet. ELectrum is already providing segwit address and transaction support. So f you want faster and cheaper transactions, start using segwit enabled wallets.
