Financially, investing in Bitcoin is very appropriate and promising in the future, many consider altcoins to be very far away from Bitcoin in terms of current investments.
Actually, having money saved in altcoins that already have quality in the market with external exchange can also provide greater profits as long as you are brave enough to put money in and are prepared to lose the most important thing, don't collect too many new altcoins, most of the new altcoins after the hype will become shitcoins.
You need to differentiate and separate between investing and saving, they are not the same. Investing can bring you profit but can also cause you to lose and even lose everything. Meanwhile, savings is where you store assets for the future or emergencies, so saving money in altcoins would be a bad idea. Altcoins are very risky, they are suitable for speculation and not for long-term investment, let alone saving.
Also, when investing in altcoins, whether new or old, careful research is required before investing. There is no guarantee that old altcoins won't become shitcoins or disappear.
