You need to know that they work by the same way, they are different chains but you can receive/send btc in there, only that the segwit addresses are cheaper, you can send bitcoins more fastly and without high fees (10% less than the legacy ones)
My brother asked me this yestearday beucase he bought a new ledger nano s thing and in the screen he had seen the device was asking for segwit or legacy blockchains. I told him to select segwit due to low fees.
If your brother is on this forum and specially, on a signature campaign; let me tell you that he is going to get banned only for sharing wallet addresess and cheating the forum.
Is there any chance to lose our bitcoin due to this selection in the future?
I hope that you are not doing that! Of course! But if you are one of the cheaters i would be in love to see how you get tagged in there.
I think the "upside" of this scaling issue, or fee problem anyway, is that people are being forced more and more to learn more about Bitcoin's tech... how to use it properly, how to be more in control, how it works... which is, arguably, the direction users should head towards to so they can help with forward adoption. I say this only because of my own experience. Perhaps if fees and confirmation times never became an issue for me, I'd never have learnt to use wallets properly. Perhaps without the fork threats (and events), I might never have needed to learn how to secure my coins.
