Some worthwhile altcoin for us to invest is Stellar, and Monero. These are two altcoins that I am very confident, I think in the near future they will grow strongly and bring a lot of profit to investors. Stellar has impressive growth rates, which provide high stability. Monero has the perfect technology, it brings privacy to the user. All transactions with Monero are completely anonymous. I believe in future Monero will be more popular and its price will increase.
