Its true that if there are many cryptocurrency that trustworthy, potential, long term holdable and safe for Investment then bitcoin comes first, afterward the Ethereum. Most of altcoins always contains risk with them while Ethereum is worth for investment even long period too. Bitcoin is flying currently and We excepted the start of altcoins season with full power, once done the btc halving. But good altcoins can give us incredible benefit if we can buy them with cheap. And there's no doubt who have done early investment with potential cryptocurrency, already increased their capital a lot along with bitcoin.
If Bitcoin is no doubt there will be stability for investment there. In fact, we bought it at the peak during the halving period this year, surely at the next halving we will get passive income from it.
for altcoins I suggest Real World Assets in Q2. see blackrock has started to take steps by creating their own coins. and it seems like the Coinmeme hype is over this month. So don't expect to invest in memecoin with conditions changing investor movements
