<prompt> Human: Me and 9 other friends are going to go a vacation in about a years time. We decided that I would be the care taker of a savings account. Each week they give me money that i put into the account. I provide a updated spreadsheet so everyone can see how much money they have put in. We are talking roughly 250 a week and 1k a month that i am given. Is it too risky to put this money in a betterment or acorns account so the money can grow in a years time. Is there any safe investment recommendations that I should consider so I can save people even more money on the vacation when the time comes.Thanks!  <response>: Absolutely too risky. Keep it in a savings account. What would your friends think if the money was worth 10 less or worse than what they had put in after 12 months? Also, Acorns fees are pretty high, especially on small balances, its a totally unnecessary service.
