Identifying a gem can be intuitively done or better still through proper fundamental analysis for crypto currency investors. It is therefore worthy to mention that many project with good proposed intentions and program get abandoned and some rugged. SNGLS and VIA are some projects that Binance is planning to delist due to the projects not doing well.
Someone I know already lost a huge fund invested in the project by following a wrong trade signal on SNGLS thinking the project will accrued some profit to his investment in this new bull flag only to get the Binance announcement of their plan delisting of the project. Of course, the price started dropping fast as like a pack of cards as people began to pull out their funds.
Investment in crypto project is investment in people or team and project proposal you're convince about and hoping it is followed through. And when that is achieved, you would have found a gem. Technical analysis will automatically fail you once something or anything goes wrong with the fundamentals of the project. Be safe, do your own research!
