We have infinite number of Alts (sh*t coins) available and irony is that people keep on investing in these coins with mindset that they will go up one day and they never. There are sh*t coins available who has price close to zero (like 0.0000001$) and you can buy thousands of such coins in just one dollar. It's about understanding the fact that there is no thing which is fully decentralised like bitcoin and alts have very short span of life.
There are theories like one must have a diversify portfolio but in Bitcoin world there is only one and only coin for investment i.e., Bitcoin. If you are thinking of investing then bitcoin must be your first and foremost choice for investment. Don't think that these Alts can move and behave like Bitcoin.
Exactly what is happening in the crypto space, all these alts are like pure gamble that evolved every four years or say after the bitcoin halving has occurred and we are in the bull run, so some of the investors throw away few dollars on this shitcoins with the expectations that it will one day pump. I am not utterly saying they wouldn’t pump but it’s a 1/10 chance in all the coins you buy and that means when the remaining 9 options actually fail you lose almost Same amount you’re earning in the one portion that gets pumped.
Furthermore I am not against buying altcoins but never treat them as an asset or a diversification means to bitcoin investment. If you have invested into bitcoin and you’re looking to diversifying your portfolio simply look into other assets like precious metals, real estate or even agricultural commodities or stocks/bonds. Picking altcoins as diversification is simply leaving your money in one sector and picking a more risky asset. Altcoins can only pump when bitcoin pumps but they can die off without bitcoin falling so why invest in Altcoins when the better option is simply bitcoin
