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 ?
Most probably if you want a safe, secure and assured investment, you would also choose to invest into the top rank cryptocurrency coins because they are the ones with the greatest potential due to the fact that it have the greatest demands and the price movement is active due to the active participation of the people in the market purchasing and investing into those coins. If I would be asked, I would preferably invest into the top rank coins because of the proven potential over time. Now in your case as a newbie learning the basics of investing into crypto, investing into top rank coins will also be the best option you could have. It's just that mostly the coins that belong to the top rank are that expensive to afford but surely worthy once purchased and invested. This strategy of investing into the top coins most of the time works because you can assure that your investment is safe with those coins and can do have potential of gaining profit, but in a matter of time depending on the situation of the market.
