In making a decision to invest in any businesses like cryptocurrencies is a very wide research, of course some of the company in minings are legits and paying and one of them is the POLARIS MINING COMPANY a mining farm on the ethereum blockchain, XRP token or the ERC20.
We don't want to lose any money while looking for a good opportunity to invest with though it kinda sad that sometimes getting into a failed/scam program can be unavoidable and that is one risk we have to face with a strong heart. This can be the reason why if there is really a good business opportunity like Polaris to come in we have to take a good look, analyze it and then decide to be a part of. Here we can be sure that there is a real business and that the tokens have assets behind them and not just another airy promises.
One can never be sure of having a 100% trust on a project especially with ICOs because of the scams and bad agendas aroud this field. One can never say that a project is legit and is real until they see a development and the team is really dedicated to this project. For example Polaris, we cannot say that it has 100% chance of succeeding but as investors and suppoters, we have FAITH that it will be. The community around the project is important too for it to succeed.
