Go for a coin with solid fundamentals that will be a good basis for the next bull run. There are only a handfull of projects actually developing new tech, pick one of those.

One coming to my mind is Stakenet XSN for example. They are the first on the world to enable LTC lightening swaps on their mainnet and also the first who brought us trustless cold staking from offline wallets (TPOS). Moreover there are several other reasons:

- pooled staking platform www.stakenet.io
- masternode as a service
- first truely decentralized DEX hosted on 1700+ masternodes
- ledger and xeeda support confirmed
- multicurrency light wallet
- own hardware devision engineering their own hardware devices which will be available for the public to buy
- CCPOS will enable you to chose in which currency you want to receive your staking rewards
