One thing for sure, is that many new technologies and improvements have been coming around the past years from rival projects, to make a stable and secure smart contract platform. If Ethereum's competitors succeed in providing secure and scalable smart contracts before Ethereum does, then ETH's place could be at risk as its rivals would rise in user adoption within the mainstream world. However, I believe that Ethereum's Casper PoS and Sharding improvements are just around the corner, to make it as efficient and secure as possible.

Stellar is one of the good coin in the market, it will not dump in a few months. Being on top 8 means that it has really a real working project. Market is just recovering, bull run just started so better hold it. Prediction is that btc price will rise again up to $20k, but I can't guarantee that. Best time to sell your coin if you will gain profit, even just 1%, it means that holding is successful. At the end of the day, it is still depends on your needs if you are gonna sell it or not.

No one use ETH expect SCAMers and suicide investors
