I am no financial advisor but however I believe this answer will age well. A few of them who look at this and actually put a few dollars o these projects may become millionaires.

Please do your own research before investing and none of what I say is financial advice.

Here we go,

Some of the projects that I believe will be top projects in 2021 are :
1. BTC : King needs no introduction, digital gold 2.0.

2. Ethereum : Finally Eth 2.0 will be here, we are already seeing the DeFi craze sweep the planet. Vitalik save our gas fees.

3. Polkadot : Polkadot Ecosystem will be the next big runner , potentially causing the next bull run.

4. The Graph : Indexing protocol, most of the popular projects use this. Mark my words, this will be a top 20 project.

5. Concordium : Dark horse of Crypto regulation and a hedge against regulation. Concordium is a blockchain having Identity verification and Regulatory framework by design. With 2020 being the year travel rule gets implemented. This one will be huge, bringing enterprises and banks into crypto through a public blockchain.

6. Tezos : We all know how this gonna run.

7. Near : Near Protocol has been having lots of developments and this one will bring value to the table. 

8. Skale : Scaling Ethereum, enough said.

9. Ripple : Ripple will keep having those scam pumps, XRP army will shill again.

10. Chainlink : We all know this Kek coin with mad fundamentals with perpetual pumpamentals.

11. SpaceChain : This one has huge partnerships, European Space Agency, NASA , and has already put satellites in space. Tim Draper low key shills this shit.

What are your picks? Which is the dark horse in your bags?
