It's a hidden gem waiting to blossom someday. Current prices are a bargain, considering the potential of the Thunder Network. It's 100 times better than Ethereum with instant transactions and near-zero fees. I'd suggest you claim some free Thunder Tokens at their official faucet here: https://faucet.thundercore.com/ Prices could boom sometime in the future as "De-Fi" becomes more popular in the mainstream world. Imagine if Thunder Token hits a price well above $10 per coin. You would make a fortune if you held coins while they were still cheap on the market.
Whenever the project will become a success or a failed experiment in the long run, it's yet to be seen. The Thunder Network is not as popular as other smart contract platforms probably because of the lack of marketing/promotion. There's no guarantee prices will go up, as people are focused on other big players in the crypto/Blockchain space. But who knows? Maybe we'll get lucky if it gets traction sometime in the future. )
