Yes, absolutely the right decision. Alcoins are not about long-term investments. Only a few of the currently known altcoins will exist in 5 years. Only in bitcoin can you be sure.
True, but some Altcoins that already have a strong community and market will also last for a long time, especially if the Altcoin platform has been widely used by everyone who is in crypto, of course the Altcoin will always last in the long term like Bitcoin.
