Yes. Ethereum seems like the preferred and most reputable platform for smart contracts. There are many good financial smart contracts being built on and for of Ethereum, e.g. dYdX, Dharma... Most of these services likely will be ready by 2019 and we will see shifts in financial sectors in the real world.
There are many other blockchains with smart contract capability and great promises, see
https://github.com/Overtorment/awesome-smart-contracts. But until there are actual real-world and live dApps on the platforms that are being used by active users, and measured by monthly active users in the scale on at least 10k, those platform will still be considered experimental.
Ethereum prices are down along with other crytpos in the bear market. But when the user activities picked up, the prices will follow suit due to supply and demand.
Nevertheless, one shouldn't bet ALL IN just based on the price. Instead, you should be focusing on the potential of utilising smart contracts to earn passive income out of the ETH that you are holding.
