2: never n trust any other coin aside from Bitcoin for long-term goals, most especially the highly centralized altcoin as there are open to external influence just like centralized exchanges are also exposed to external influence.
Writing is one easy thing to do but will you put your money where your mount is? Bears give people reasons to reason like this but will they kept to their promises in the bull market when everything seems to be giving people profit. One thing about altcoins investment is that, there'll always be one better than the one you're thinking will last forever and they can just disappear from the market without much been done. Altcoins has given people some decent profits in the last years but they have done more harm to a large range of speculators as the losses are always more than those profiting.
Investing in altcoins is just too risky, some people have traded altcoins and realize good profits and many traded and loss all they had. Altcoins is good for experience traders that can take the risk to invest or trade on it, I don't think it is proper for young investors to consider to invest in altcoins because of to make good profits. People take the risk of investing altcoins for greed to get quick money, the probability of not having good trade and investment in altcoin is very high. During this bear market many altcoins could not not survive the bear market. Bitcoin is the most reliable and trusted for investment.
