Indeed it is scary if you are investing in new projects but if you are investing in ETH, you are going to have peace of mind. But yes, $30k is quite huge enough to put into a risky investment even though we know that ETH can be trusted or ideal for long-term investment. If ever I have that amount in hand, I will put some amount to other form in investment or start a business as in the case that we lose in crypto, we still have other way to recover those losses from other investment and income resources.
Even with ETH, I am not that convinced that it will make me not regret investing, bitcoin has not failed me so far so I will just put all my money on it no matter what because I am better off profiting in bitcoin as much as possible than splitting my investments in different altcoins that are full of uncertainties. Maybe other users have the heart to be able to do that but not me, the lesson learned is just too expensive for me. If I had that amount, I would probably just allocate 1k USD in ETH only and then try to wait for bitcoin to go down again so I can get a good value out of the 29k that is left or what is going to be left when I spend some money for the stuff that I want to buy for a long time now.
30k is a scary amount to invest in altcoins even if you know that an altcoin boom is coming in the horizon, I've learned my lesson about altcoins last season so I don't want to repeat the same mistakes, I'm better off just waiting for my bitcoin to grow and hopefully sell it at a favorable price and then hopefully get in quickly to it. OP's plan is feasible and attractive to follow but that will be the possible scenario if all the stuff that OP mentioned exactly happened and we know that the cryptocurrency market is a volatile market and you will never know what's going to happen even if you are good at market analysis.
Investing in altcoins shouldn't be done with much money but only the amount that you can afford to loss. Altcoins can be hype by the dev and the price will pump 100X and before you know it,you that invested at that time becomes the loser because in no time,it will turn to zero,leaving you frustrated.
This I can agree and not just with altcoins, everyone is encouraged to do the same with bitcoin, just invest what you can afford to lose. This advice is a timeless one because it is the truth and it is making sure that you are not going to go overboard with your investing journey and at the same time makes you balance your needs for investing to save for the future and having some money to spend for the present. That is why I do not go for altcoins now, the potential of it being a rugpull is just too much and it sucks that you are going to be the one that will be gullible to give them your money.
