Meme coin mania and whether to consider investing in FLOKI, PEPE or Dogwifhat:

Pros:

1. Meme coins are seeing massive price surges and huge percentage gains driven by hype and social media trends. FLOKI is up 67%, PEPE 32%, and new meme coin Dogwifhat up 25% on March 8th.

2. They provide an opportunity for potentially large and rapid gains for investors willing to take on high risk.

3. The hype and community enthusiasm around meme coins can be a powerful driving force behind further price increases.

Cons:

1. Meme coins are incredibly volatile and speculative. The gains can evaporate just as quickly as they accumulated based on shifting memes/trends.

2. Most lack real utility or use cases beyond being a vehicle for speculation. Their long-term prospects are questionable.

3. They are a very high-risk investment. Investors could lose a substantial portion or all of their investment capital.

Key Considerations:

1. Only invest what you can afford to lose completely given the high risk nature of meme coins.

2. Do thorough research on each project - team, roadmap, tokenomics etc. Don't invest based on hype alone.

3. Consider allocating just a very small portion of your portfolio to any meme coin investments.

4. Have clear exit strategies and price targets in mind.

Overall, meme coins can provide opportunities for rapid gains but are extremely speculative and risky. More risk-averse investors may want to avoid them entirely or take only very small positions. As always, thorough research is crucial before any cryptocurrency investment.
