Cryptocurrency price changes may be severe on a daily basis, and I've seen that 10-20% is typical, but for Talk Token, in my opinion, even though the price is still below 0.00000001 and has been listed on Yobit, it is highly recommended to do a TA analysis first about coins/tokens to minimize the risk in investing whose initial intention is to profit, so it ends up losing and in vain.
TALK is cryptotalk token not owned by yobit
Cryptotalk is being promoted by Yobit before. Even technically we think that TALK is not owned by Yobit directly, there's an affiliation so we can conclude it was under by Yobit in any case. Yobit is known for pumping and hyping small-cap to dead coins. If you are a new player to crypto, it's not recommended to test your luck there since the hype will just last for 1-2 days or even just an hour. Don't be deceived by their expected market value.
There are lots of coins you can play around. Choose those instead unless you are shilling that coin here too.
