But as a newbie, I want to tell you to keep Bitcoin in your investment and not any other shitcoin/meme coin other than Bitcoin because you can expect to achieve success in long-term preservation of Bitcoin, but if you keep shitcoin/memecoin in your investment portfolio, then I don't know if you will be successful in long-term investment.
Altcoins die, shitcoins die, meme tokens die but Bitcoin will continue to be strong and alive in this market. Choosing Bitcoin is a best choice you can make for your investment portfolio in this cryptocurrency market. It's like you pick the golden investment asset among thousands of useless and scam assets (altcoins).
The advice of picking Bitcoin, or even only Bitcoin for an investment portfolio is very common, but unfortunately most of newbies ignore Bitcoin and decide to invest in shitcoins.
How many cryptocurrencies have failed (dead coins)?It will be very important for you to only hold BTC but you can start from now if you want because there is still plenty of time to buy Bitcoin.
Hold it in your cold storage.
Hold it in your open source, non custodial wallet.
Hold it in a wallet that you already made wallet backups and test wallet backups for recovery.
DON'T hold it on centralized exchanges, in custodial wallets.
Reminder: do not keep your money in online accounts.
