Doge can give big profits if we're lucky since meme coin really have bigger risks other than normal altcoins such ETH, BNB, SOL etc. rather than trying with our luck it's better to invest in something clear in terms of utility, community, team member, and roadmap. We're going to have altcoin season so it's better to choose top altcoins rather than still gambling with meme coin. Don't forget to make investments based on your research because lots of influencers will ask you to invest under them or follow their movement.
I don't know how safe it is to invest in meme coins like Doge coin. But I made good amount of money from Doge long ago. Now I am not interested in investing in meme coins. It is very difficult to make money by investing in them. So I prefer to invest in bitcoins and altcoins. I know that if you keep investing in them, the chances of getting profit are very high.
