Will i need to use bech32 at some point in the future adoption of segwit ?

If you like. No reason why you have to. It's just a bit cheaper for you if you do (as spending transactions will have lower weight).

@PieterWuille Did you mean using bech32 addresses we pay less tx fees?

Yes, if you **receive** coins using bech32 addresses (as in: you're giving bech32 addresses to others who pay you), it will (over time) become cheaper for you to send coins. The difference for typical transactions is around 20%.

The address you need to sent to is **2N4dpih8KAdfJyXn2vhWixUwmYJ6DBfeRM1**, as that is the output of `getnewaddress`.

That's a P2SH-P2WPKH address, which became the default in 0.16. It is not a legacy address, but a P2SH-embedded segwit address.

If you want a P2WPKH (native, bech32) address, you should tell `getnewaddress` that is what you want, by calling `getnewaddress "" "bech32"`. Alternatively, you can tell `bitcoind` that you always want by putting `addresstype=bech32` in `bitcoin.conf`.

Never try to convert one address type into another yourself. `validateaddress` is giving you information about the address you passed in. `bitcoind` does not expect payments to anything but the address that `getnewaddress` gave you.
