Lightning Network and Segwit adoption is already progressing well in the background so my honest opinion is that nothing else should be improved with BTC.
Devs are already working on Lightning Network, but with Schnorr multisig is handled like a regular signature, which make transactions more secure.

Absolutely have some ways to field search bitcoin users and got them.buy sell tracker in your country.2FA verification of your NIC card. exchange KYC verification. If you do not do transaction activity in Online Shop, or other official store, I think you will be safe.
