Dont hold alternative cryptocurrencies for the long term
and if you must own them just know you are just
gambling with your money, because they can go
from100 to 0, so altcoin is worthless for the long term.
So many newbies are confused with Bitcoin and think that it is the same as other cryptocurrency because they don't have the knowledge. Bitcoin is king and every other crptocurrency is a duplicate of it. If you want to invest in altcoin as a newbie, you shouldn't do that because you will end up regretting if you don't trade it after a high pump because it will definitely go back to zero. Most altcoins are scam projects.
So haven said that I will like to add to your advice for Newbies.
1. Never you store the seed phrase to your wallet carelessly because that's the key to your fund.
Your seedphrase is as important as your bitcoin, and if you don't have proper back up,if you lose your phone or flash your PC ,you will end up not having access to your coin. Another risky aspect of not keeping your seedphrase safe is that someone can see it and take it as an advantage to steal your coins fr your wallet.
