I believe that anytime is a good time to enter crypto, but we should all say the following things to our coworkers, neighbors, friends, family or relatives:
1. Read the BTC whitepaper before buying crypto; any investor should understand the object of his investment and all crypto whitepapers are based on BTC;
2. Investing is like running a marathon, you have to be in it for the long run and for the good reasons, not care about BULLS and BEARS;
3. Invest only what you can afford to loose because crypto is a social experiment not backed by any government or financial institution;
4. Do not invest more than 5% of your capital because crypto is an Extremely High Risk investment as opposed to the stock market which is a High Risk Investment;
5. Altcoins carry an even greater investment risk; hundreds of altcoins have gone from Hero to Zero and BTC is the only crypto to have recovered from all bear markets;
6. Do not take out loans or use credit cards to buy crypto; you do not need a 30% interest on a crypto which can go down to 0 in just a few weeks;
7. Use Dollar Cost Averaging to buy crypto; decide on an amount which you can spend easily every month, every two weeks or every week to buy crypto; Dollar Cost Averaging will safeguard an investor from price fluctuations in the long run;
8. Learn to safeguard your funds; in this social experiment called crypto you are the only one responsible for the security of your funds because your are both the bank and the client at the same time
9. Diversify your portfolio in time, don't rush it, focus at first on BTC;
10. Investing is not Trading; leave Trading to the profesionals and fools.
