The top altcoins are the most inefficient investment of your money as they do not outperform bitcoin investments by much, even at times yielding inferior returns. If altcoins can't beat bitcoin in terms of investment appeal, then why carry your money into these altcoins. SHIB has long been in that category of coins that went high and is now slowly dying. SHIB is a memcoin, and investing in memcoins is always attracted by probable high returns. It makes no sense to expect high returns from a token that has already managed to grow by a million percent.
