But i just create wallet for doge coin

Should i buy coin now?
Every huge hodlers of dogecoin or users from pump-dump groups be like, "Buy Dogecoin as it'll hit $1" and FA (Fundamental Analysis) be like,"Am i joke to you!"

Better to stay out from those coins/tokens which don't have that much strong fundamental use-cases in the long run. Instead of taking entry into dogecoin, better to take trades on other alts according major events or TA, IMHO.
