You must choose it by yourself. Everone have some favourite altcoins, but thats doesnt mean, that they are profitable to invest.
This is true, but with ALLLLL the shitcoins on the market today it's impossible to keep track of the ones that are actually useful. So asking a community of people who are dedicated to finding the good ones is not a bad start really. Especially since we are nearing the peak of midagame.
It's no question that Monero will go up still. It's going to. It's the first to do what it's done, but that doesn't necessarily mean it's the best. It means it's the most popular and the most proven, for now. That is why I have invested in Monero, but two that I have recently picked up and see a great deal of potential in for the price are:
SPECTRECOIN and
SYSCOIN coin.
These two coins have not invested the marketing capital to propel them into "well-known" status but the community support is and future utility are great for both of them. But the tech is strong.
There's much reason to download blockmarket even if you don't invest in SYS. It's a market that takes cryptos. It's like EBAY or AMAZON for cryptos. Getting away from FIAT and Credit will be an important step for financial security. Blockmarket is setting itself up to aid in the process of decentralization and adding value to crypto-currencies across the board. SYSCOIN is used to make a listing. If you intend to sell on the market then you should get some while it's cheap. But if you want a place to USE your cryptos instead of just altering it to fiat so that you can perpetuate the current system that Satoshi hoped to free us from... BLOCKMARKET is a good start.
SPECTRECOIN has a "tech first" approach and the efforts, aside from code, are left entirely up to the community. It's grassroots. No organizational funding, just a group of people who want to keep their financial lives private and are willing to put their time and effort behind seeing that happen. With two cryptographers on board, full-time, and a community funded information campaign underway I can see SPECTRECOIN (XSPEC) easily becoming a valuable commodity. What's better is that YOU can actively take a part in that. You needn't rely on a team of people to see it to fruition. YOU can assist in making it happen.
