Im thinking if i need to change my wallet to a btc wallet with a segwit.
Whats the difference between btc wallet and btc wallet with segwit? Is it possible to transfer btc from my btc wallet to btc segwit wallet? Is it better to use the wallet with segwit?
Yes you are able to switch to using segwit enabled wallet and send your bitcoin to it, but it will cost you some fees, because of big centrelized wallet services like Coinbase and Blockchain who have not yet supported it, switching from them to a segwit wallet will come at a cost, your transactions may have lower transaction time and lower fees, but you are going have to buy a harware wallet like LegerNano S or Trezor who supports this technology.
