To invest one must take risk, without taking risk investment is never possible but we have to make sure that we are taking risk in right place or taking risk in wrong place. Taking risks in altcoins to have bitcoins is definitely foolish.
As we have to invest through money, it is our responsibility to ensure maximum security of money. Bitcoin is safe and Bitcoin will definitely guarantee you money but altcoins will never guarantee you money. A Bitcoin investor has high hopes that his investment will never fail and he will never be promoted by investing in Bitcoin. Such belief of an investor towards Bitcoin is enough to invest in Bitcoin. Since we have knowledge, we have to put that knowledge to good use. Instead of depending on others, I have to find out by myself where my money will be safe as well as where my money will grow if I invest. When a person tries to use his knowledge to know these things, he can find the right investment medium and that must be Bitcoin.
Taking risks is not the issue; what is important is that you take risks that are worthy of being taken, rather than risks that have no future or whose future is uncertain. When we talk about cryptocurrencies and include altcoins, you'll see that from the start of cryptocurrencies, only altcoins have fled the market multiple times due to market volatility. If it is about strength and a solid investment, it should be bitcoin because no other altcoin would exist today and would not have been compromised if bitcoin was still standing.
Most are simply hiding behind the plumage of bitcoin and can only utilise bitcoin as their reserve currency if things do not go good for them in the long run. Do you still need to be convinced that anltcoins are just high-risk, gamble investments after all of this? You'll never know the direction of these coins, but most of them will lose their value and their holders or investors or trades will lose all of their investments in them.
