whats the best currency to invest?

BTC is always a safe bet in crypto. Almost all of the infrastructure is built around BTC. That being said, you will see less risk in BTC and therefore less gain. I personally like privacy coins and coins that could serve as a good store of value. For that reason I really like Beam. They have created a coin that is really fast, has a finite supply, and is in my opinion the best all around privacy coin at the moment. *This is subject to change without warning at any time. Crypto technology is always improving and others becoming obsolete. You really need to do a lot of research and then stay involved once you invest.

Bitcoin? Due to acceptant an over all acceptance among society as a whole.

Ethereum is highly recommended. Some people says that it'll have a boom like Bitcoin

I'm thinking of investing into crypto currencies, but I'm skeptic whether or not it will work out in the long run.

just hodl chainlink bro, 1000 usd eoy
or v-id (vidt)

There is too much price manipulation and lack of transparency in Bitcoin to safely invest. I'd just stay on the sidelines and watch the fireworks.

Follow the money..... i have some npxs (Pundi X)
They are active and have real life solutions for payments.

The most important thing to mention is, that wether its BTC or LTC or or or you should only invest money which you can afford loosing. The investment in cryptocurrencies is highly speculative.
Maybe the investment into a "mining group" is another option instead just buying coins and hoping their value will raise. Especially BTC is overvalued in my opinion. And that said, many other currencies are
connected to the value of BTC making it a rollercoaster.

What about IOTA? Have any of you guys tried it? I'm really curious since my brother started with it and he's getting money but idk how good is it.

Bitcoin is the best Best for investment But Ripple and Bitcoin Cash are also good ones
