Hi Everyone,
As advised I am trying to learn the basics of crypto first.
Most of the suggestions mention investing in top ranked coins. My question is, does it always work? As far as I understand, the market is vulnerable and affects almost all the coins from top to bottom. How then you determine which ones would stay ?
For me it is not, I do invest in coins which It think is good, reliable and no hidden information. It is right to choose in top coins but sometimes I feel like scary to invest with it.

Yes . It can be seen that the Top Coins are safer and more stable than altcoins. Such currencies are very reliable and can bring more development. But you need to have more capital compared to less reputable currencies
