If you take the top 5 coins for investment then this is not as risky as investing in the top 100 coins of the crypto market!
Those who invest in top coin in the market is in the right path. Analyze the market first before investing anyway all here in crypto is very risky. Invest on your affordable amount and don't all in when investing in crypto.
For now the price of many coin are down so I guess it's the right time to buy, risky is part of crypto currency but for me as long as you buy at the lowest price you don't need to worry.
